In
Terry v. Ohio,
the Supreme Court held that a police officer may stop and detain a person briefly for investigative purposes if the officer has a reasonable suspicion, supported by articulable facts, that criminal activity “may be afoot.”
I.
In the case sub judice, the Charles County Sheriffs Department received a tip from a confidential informant. Claiming that he had both witnessed and videotaped a drug transaction *495 in front of the Saint Charles Towne Mall, the informant produced a videotape showing two men, John Carlson, and the petitioner, Reginald Longshore (“Longshore”), get into a Ford Expedition, which was parked in the mall parking lot and remain there for a short time, while a third person stood by the driver’s door. No drugs, paraphernalia, or money could be seen on the videotape. The police detective, Smith, nonetheless, set up surveillance at the mall and with regard to Carlson’s vehicle, a Toyota.
Longshore drove away from and, a short time later returned to, the mall. Upon his return, he was followed into the mall by a second detective, Clark, who then observed him meeting with the two people with whom he earlier had been seen, and recorded, in the videotape. As was the case in the videotape, although the three people were together, no drugs actually were observed on this occasion.
When Carlson drove away from the mall, his car was stopped by the police. He consented to being searched. According to the officers, uncovered in the search was a “quantity of marijuana and cocaine.” 1
At about the same time, a certified drug sniffing dog, Tonya, was brought to the mall to scan Longshore’s Ford Expedition, which was again parked on the mall parking lot. Longshore was, at the time, still inside the mall. Tonya scanned Long-shore’s Expedition and two other cars in the parking lot, with negative results; Tonya did not alert to the presence of any drugs in any of the cars.
Subsequently, Longshore left the mall, driving his Expedition. He was stopped by a third detective, Detective Edge. Detective Edge informed Longshore that he believed that there were drugs in his vehicle. When Longshore declined to consent to a search of the vehicle, Detective Edge, although aware of the prior negative scan, called for Tonya to scan the *496 Expedition again. While waiting for Tonya to arrive, Long-shore was placed in handcuffs.
Tonya arrived within two minutes and the scan was conducted. During this second scan, the driver’s side window was down, and, as with the first one, the engine was turned off. Upon scanning the exterior of the vehicle, this time, Tonya alerted, indicating the presence of drugs in the area of the rear “wheel well underneath the vehicle.” A subsequent search uncovered no drugs in the rear area of the vehicle or underneath it, however. Tonya then was allowed into the vehicle, at which time she alerted to the center console area of the ceiling. A search of that area uncovered a pill bottle containing crack cocaine. 2
Longshore was indicted by a Charles County grand jury on charges of possession of cocaine with intent to distribute and possession of cocaine. He moved, prior to trial, to suppress the pill bottle and the cash as the fruits of an illegal search of his truck and of his person. The Circuit Court for Charles County denied the motion. Regarding the stop of Long-shore’s vehicle, the court ruled that the informant’s videotape and the drugs found in Carlson’s car provided sufficient reasonable suspicion to warrant the stop, which it found continued for no more than 15 minutes before the discovery of the drugs in the ceiling console. The court did find that Longshore had been handcuffed at the scene before Tonya arrived to perform the second scan.
The suppression court also addressed Tonya’s reliability. It noted that Tonya’s training officer and custodian “testified at great length as to Tonya’s training and certifications and they weren’t really challenged by anyone at the hearing.” The court concluded that “Tonya is a reliable indicator as to the presence of controlled dangerous substances.”
*497 Regarding the search of Longshore’s vehicle, the court ruled that probable cause existed once the dog alerted to the presence of drugs. It also indicated that the videotape alone gave the police probable cause to search.
At trial, the officers involved gave testimony that was generally consistent with the evidence adduced at the suppression hearing. Longshore was subsequently found guilty of possession of cocaine with the intent to distribute and was sentenced to fifteen years incarceration, the first ten of which were to be served without parole. An appeal to the Court of Special Appeals was noted by Long shore. That Court, in an unreported decision, affirmed the trial court judgment.
The Court of Special Appeals addressed the question, “Did the suppression court err in denying the appellant’s motion to suppress the evidence seized from his vehicle and his person?” Longshore’s argument was similar to the one he makes sub judice, namely, that, when he was handcuffed, he was effectively arrested, and that the police did not, at that time, have probable cause to effectuate a warrantless arrest. The State argued, in response, that the initial stop was simply a detention and that it was supported by reasonable articulable suspicion. Even if the detention constituted an arrest, it maintained, the police possessed probable cause to justify it. The Court of Special Appeals held that the stop was an arrest, not a detention, but concluded, ultimately, that the stop was supported by probable cause.
Longshore filed, in this Court, a petition for writ of certiorari, and the State filed a conditional cross-petition.

Both petitions were granted by this Court.
Longshore v. State,
*498 A.
When an appellate court reviews a trial court’s grant or denial of a motion tо suppress evidence under the Fourth Amendment, it will consider only the facts and information contained in the record of the suppression hearing.
State v. Nieves,
An appellate court further will view the evidence and all reasonable inferences drawn from that evidence in the light most favorable to the party prevailing on the motion, in this case, the State.
Nieves,
*499
An appellate court, however, under an independent
de novo
review standard, must consider the application of the law to those facts in determining whether the evidence at issue was obtained in violation of the law, and, accordingly, should be suppressed.
Nieves,
With this in mind, we turn to the case sub judice. The Court of Special Appeals held that, when Longshore was placed in handcuffs, he was effectively arrested. Having so held, it needed also to decide whether there was probable cause to support that arrest.
The power of the Court of Special Appeals, as an appellate court, is, like this Court’s and any appellate court’s, plenary; it is bound by the record in making those determinations, however. Making factual determinations,
ie.
resolving conflicts in the evidence, and weighing the credibility of witnesses, is properly reserved for the fact finder.
See Binnie v. State,
The Court of Special Appeals did not err in deciding that the petitioner was arrested, rather than, as the trial court found, merely detained. As we shall see later, however, there was no substantial basis for its conclusion, if not finding, that probable cause existed when the petitioner was arrested.

The Fourth Amendment to the United States Constitution, applicable to the States through the Fourteenth Amendment, provides that “the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated ... and no Warrants shall issue, but upon probable cause____” U.S. Const, amend. XIV.
See also Mapp v. Ohio,
A warrantless arrest of an individual in a public place for a felony, or a misdemeanor committed in an officer’s presence, is consistent with the Fourth Amendment if the arrest is supported by probable cause.
United States v. Watson,
Moreover, “[p]robable cause exists where ‘the facts and circumstances within [the officers’] knowledge and of which they had reasonably trustworthy information [are] sufficient in themselves to warrant a man of reasonable caution in the belief that an offense has been or is being committed [by the person to be arrested].”
Brinegar v. United States,
In Maryland, the perimeters of an arrest were defined in
Bouldin v. State,
“It is generally recognized that an arrest is the taking, seizing, or detaining of the person of another (1) by touching or putting hands on him; (2) or by any act that indicates an intention to take him into custody and that subjects him to the actual control and will of the person making the arrest; or (3) by the consent of the person to be arrested____ It is said that four elements must ordinarily coalesce to constitute a legal arrest: (1) an intent to arrest; (2) under a real or pretended authority; (3) accompanied by a seizure or detentiоn of the person; and (4) which is understood by the person arrested____
“We have defined an arrest in general terms as the detention of a known or suspected offender for the purpose of prosecuting him for a crime. McChan v. State,238 Md. 149 ,207 A.2d 632 (1965); Cornish v. State,215 Md. 64 ,137 A.2d 170 (1957). Our cases make clear ... that in ordinary circumstances ‘there is a detention only when there is a touching by the arrestor or when the arrestee is told that he is under arrest and submits[, but where] there is no touching, the intention of the arrestor and the understanding of the arrestee are determinative, for in order for there to be an arrest in such case, there must always be an intent on the part of one to arrest the other and an intent on the part of such other to submit.’238 Md. at 157 ,207 A.2d at 638 . Ordinarily, therefore, there can be no arrest where there is no restraint or where the person sought to be arrested is not conscious of any restraint.”
In
Grier,
Addressing the nature and effect of the evidence elicited by the question, “What, if any explanation did the defendant offer to you [as to] why he was or why this was taking place?,”
id.
at 251-52,
“After Grier came out of the dead-end alley, the officers immediately arrested him. The officers pursued Grier, ‘got’ him, and put him on the ground. Once [Grier] was on the ground and in the custody and control of the police officers, he was certainly under arrest. See Bouldin v. State,276 Md. 511 , 515-16,350 A.2d 130 , 133 (1976). Although Officer Harley may have had the right simply to detain and question [Grier] before placing him in custody, he did not do so.”
Morton
also involved the admissibility of challenged evidence.
The day following the robbery, officers, acting on information from a pharmacist, stopped the defendant and frisked him.
On this set of facts, this Court held:
*505 “We think it clear that the appellant was arrested when Rice removed him from the recreation center and placed him under guard in the police patrol car. We said in Bouldin v. State,276 Md. 511 ,350 A.2d 130 (1976), that an arrest is the taking, seizing or detaining of the person of another, Inter alia, by any act that indicates an intention to take him into custody and that subjects him to the actual control and will of the person making the arrest. On the record before us, Rice’s manual seizure of the appellant and the subsequent restraint of his liberty plainly constituted an arrest, there being nothing to show that the appellant voluntarily consented to the restrictions placed upon his frеedom by the arresting officer.”
In a case decided by the Court of Special Appeals,
Dixon v. State,
After preliminary surveillance of the defendant, during which photographs were taken, the police arrived at the parking garage.
The Court of Special Appeals, citing Terry and several cases that followed it, opined:
“As we see it, the events in the garage exceeded an investigatory stop under Terry and its progeny. Accordingly, we do not agree with either the State or the trial court that appellant was merely detained prior to the car search. Instead, we conclude that the officers arrested appellant at the time they blocked his car, removed him from h is vehicle, and handcuffed him.”
There are instаnces in which a person, who is not under arrest, may be detained. Without effecting an arrest, a police officer with reasonable suspicion, supported by articulable facts, that criminal activity “may be afoot,” may stop and detain a person, briefly, for investigative purposes.
Terry,
The reasonableness of a
Terry
stop is determined by considering “[w]hether the officer’s action was justified at its inception, and whether it was reasonably related in scope to the circumstances which justified the interference in the first place.”
Id.
at 20,
Reasonable suspicion is, to be sure, a less demanding standard than probable cause.
United States v. Sokolow,
“While there is no litmus test to define the ‘reasonable suspicion’ standard, see Ornelas v. United States,517 U.S. 690 , 695,116 S.Ct. 1657 , 1661,134 L.Ed.2d 911 , 918 (1996) (noting that it is impossible to articulate, with precision, what ‘reasonable suspicion’ means), it has been defined as nothing more than ‘a particularized and objective basis for suspecting the particular person stopped of criminal activity,’ United States v. Cortez,449 U.S. 411 , 417,101 S.Ct. 690 , 695,66 L.Ed.2d 621 , 629 (1981); see also Ornelas,517 U.S. at 695-96 ,116 S.Ct. at 1661 ,134 L.Ed.2d at 918 , and as a common sense, nontechnical conception that considers factual and practical aspеcts of daily life and how reasonable and prudent people act. See Ornelas,517 U.S. at 695 ,116 S.Ct. at 1661 ,134 L.Ed.2d at 918 .”
Id.
at 415,
“The officer, of course, must be able to articulate something more than an ‘inchoate and unparticularized suspicion or “hunch”.’ The Fourth Amendment requires ‘some minimal level of objective justification’ for making the stop. That level of suspicion is considerably less than proof of wrongdoing by a preponderance of the evidence. We have held that probable cause means ‘a fair probability that contraband or evidence of a crime will be found,’ and the level of suspicion required for a Terry stop is obviously less demanding than that for probable cause.”
Sokolow,
In addition to stops and brief detentions, other intrusive police actions are permitted when they are conducted in furtherance of the goal of protecting the safety of the officer.
See State v. Smith,
“... has reason to believe that he is dealing with an armed and dangerous individual, regardless of whether he has *509 probable cause to arrest the individual for a crime. The officer need not be absolutely certain that the individual is armed; the issue is whether a reasonably prudent man in the circumstances would be warranted in the belief that his safety or that of others was in danger. And in determining whether the officer acted reasonably in such circumstances, due weight must be given, not to his inchoate and unparticularized suspicion or ‘hunch,’ but to the specific reasonable inferences which he is entitled to draw from the facts in light of his experience.”
Terry,
As the Court of Special Appeals noted in its unreported opinion
sub judice,
the permissible scope of a
Terry
stop has expanded in the past few decades, allowing police officers to neutralize dangerous suspects during an investigative detention using measures of force such as placing handcuffs on suspects, placing the suspect in the back of police cruisers, drawing weapons, and other forms of force typically used during an arrest.
United States v. Tilmon,
Nevertheless, Maryland has recognized very limited instances in which a show of force, such as placing a suspect in handcuffs, is not an arrest. This Court has upheld the use of such force when done to protect the officer,
see In re David S.,
In
In re David S.,
a juvenile defendant was adjudicated delinquent by the District Court of Maryland sitting in Mont
*510
gomery County as a juvenile court,
5
based on a finding that he possessed a controlled substance with the intent to distribute. Subsequently, an officer with the Rockville City Police Department was engaged in the surveillance of a house on Moore Drive, which was believed to be an open air drug market.
Later that same evening, the officer spotted Hall and David S., a juvenile, walking together on Ashley Avenue. When they stopped in front of an abandoned building,
The officer radioed other officers to stop the individuals.
David S. claimed that he was seized and arrested without probable cause.
“In the case at bar, we hold that the police had reasonable suspicion, supported by articulable facts, to believe that [David S.] committed, or attempted to commit, a crime and that he had a gun in his waistband. [The officer] saw [David S.] and Hall engage in what appeared to be a burglary, and he saw [David S.] place a dark object, which looked like a handgun, in the front of his waistband. Therefore, the police were justified in conducting an investigatory stop of [David S.] and Hall.
“We hold that the stop was a legitimate Terry stop, not tantamount to an arrest. Several police officers conducted a ‘hard take down’ of [David S.].... The officers, with their weapons drawn, forced [David SJ to the ground and placed him in handcuffs. This conduct was not unreasonable because the officers reasonably could have suspected that [David SJ posed a threat to their safety. Considering the totality of the circumstances, as they appeared to the officers at the time, in order to maintain their safety, handcuffing [David SJ and placing him on the ground for a brief time was reasonable and did not convert the investigatory stop into an arrest under the Fourth Amendment. Although this is a severe form of intrusion, we conclude that under the circumstances, it was reasonable.”
In
Trott,
the defendant was stopped by a police officer, when the officer noticed him, shortly after hearing a loud
*512
crash, pushing a woman’s bicycle, “with a ‘kid’s tote ... attached to the back’” and containing a number of items, including a snowblower, weedwacker, tire, and tow hitch, towards him.
As the field interview progressed, the defendant became more “nervous” and “jittery.” Worried that the defendant may have heard his radio transmission, the officer placed the defendant in handcuffs for, as he put it, “his and my safety.”
The defendant claimed that, even if the initial stop was justified, his being handcuffed turned the stop into an arrest that was not supported by probable cause.
*513
The intermediate appellate court held that, under the factual circumstances surrounding the defendant’s detention, the police officer’s use of handcuffs was appropriate.
The Court of Special Appeals warned, however:
“This is not to suggest that every time a police officer handcuffs a suspect that that restraint is not an arrest. In fact, in most instances, placing a suspect in handcuffs does amount to an arrest, which must then be supported by probable cause.”
Id.
at 121,
The petitioner argues, as he did in the Court of Special Appeals, that, when he was asked to step out of the car and placed in handcuffs before the drug dog’s second scan, he was effectively arrested. Like the Court of Special Appeals, we agree with this argument. Having reviewed Grier, Morton, Dixon, In re David S., and Trott in context, we hold that Longshore was arrested when he was asked to step out of the car and placed in handcuffs, and that no special circumstances existed that justified the police officers placing him in handcuffs. The officers conceded that he was stopped because they believed him to possess drugs. Unlike the circumstances in In re David S., there was no suspicion that a violent crime had occurred, nor any reason to believe that Longshore was armed or dangerous. The arresting officer acknowledged that, despite Long shore’s nervousness, he was cooperative and did not exhibit any threatening behavior. The officers did not indicate that they were, in any way, concerned for their safety. Moreover, there was no reason to believe that Long-shore was a flight risk. There was no indication by the police that they believed, nor any objective basis for concluding, that Longshore would run. In addition, the incident occurred in the middle of the day, not at 3:30 a.m. as in Trott. We agree with the Court of Special Appeals that:
“There was no evidence elicited at the suppression hearing that the police handcuffed appellant because of safety or flight concerns. Detective Edge testified that appellant was *515 cooperative, and there was no evidence suggesting that he was a flight risk. Without more, we agree with appellant that when he was handcuffed, the police had effectuated an arrest.”
Because Longshore was neither a flight nor safety risk, there was no justification for placing Longshore in handcuffs. This was, therefore, no mere detention; it was, in fact, an arrest. Consequently, to be a valid arrest, probable cause was required.
Accordingly, we reject the State’s argument that the arrest was nothing more than a detention. The State contends that “[a] step-by-step analysis of the circumstances shows that the police initially conducted a brief detention, or
Terry
stop, that was justified by the reasonable suspicion that Longshore had drugs in his vehicle and arrested him when the drug detection dog alerted to the presence of drugs in the vehicle.” The State asserts that a “totality of the circumstances” analysis should apply.
In re David S.,
Citing
In re David S.
for the proposition that neither handcuffing nor pointing a gun at a suspect necessarily transforms a stop into an arrest,
The State’s reliance on
Farrow v. State,
In
Farrow,
the police set up surveillance on a jewelry store property that had been robbed by two African-American men, and, over the course of two days, observed two men, one of whom was the defendant Farrow, acting suspiciously, walking and driving back and forth in front of the store.
Farrow argued that, even if the stop were justified, the means used to detain him were unreasonable, and converted the stop into an arrest that lacked probable cause.
“The distinction between a Terry ‘stop’ and an arrest, then, is not in the method of detention, but rather has to do with the length of the detention, the investigative activities during the detention, and whether the suspect is removed to a detention or interrogation area....
* * * *
“... we hold that, in this situation, where police were facing men that were strongly suspected of being armed robbers, the officers were justified in taking complete control of the situation for that period of time necessary to accomplish the ‘frisk.’ The need for further investigation was pre-empted when an illegal handgun turned up within the lawful perimeters of the ‘frisk.’ ”
The State does not explain how this case is any different than
Trott
or
In re David S.
We have already confirmed that police officers, in certain situations, such as those evidencing the need for officer safety and to prevent flight, have authority, albeit limited authority, to use force to enforce a stop. Neither of those circumstances is present in the case
sub judice. Farrow,
therefore, is inapplicable, as Longshore was not suspected of being armed and, unlike in
Farrow,
an illegal handgun was not later discovered, thus providing some validation for any suspected dangerousness. Nor is
Lee v. State,
The State also cites
Ferris v. State,
“Although the inquiry is a highly fact-specific one, courts have identified certain factors as probative of whether a reasonable person would have felt free to leave.... These factors include: the time and place of the encounter, the number of officers present and whether they were uniformed, whether the police removed the person to a different location or isolated him or her from others, whether the person was informed that he or she was free to leave, whether the police indicated that the person was suspected of a crime, whether the police retained the person’s documents, and whether the police exhibited threatening behavior or physical contact that would suggest to a reasonable person that he or she was not free to leave.”
The State ultimately argues that “[u]nder the totality of circumstances here, where Longshore was placed in handcuffs for several minutes pending the arrival and the scanning of the vehicle by the drug detection dog; where Longshore appeared to be ‘extremely nervous,’ and the police were aware of Longshore’s prior drug arrests, the actions of the police were reasonable.” This argument is unavailing. First, as already noted, Lоngshore was not a flight risk nor was he considered dangerous. There was no reason to put him in handcuffs while awaiting the drug detection dog’s arrival. Moreover, this Court has cautioned against, “placing too much reliance upon a suspect’s nervousness when analyzing a determination of reasonable suspicion.”
Ferris,
“Prior drug arrests do not necessarily yield reasonable suspicion that an individual is secreting weapons or drugs *519 on his person at the time of his arrest on a drug offense, because to allow the reasonable, articulable suspicion standard to be satisfied based upon a person’s status, rather than an individualized assessment of the circumstances, would undermine the purpose for requiring officers to justify their reasons for searching a particular individual.”
Nieves,
Penultimately, the cases that the State cites for the proposition that it was reasonable for officers to assume that, “where *520 drugs are, weapons are as well,” are negated by the State’s evidence, the testimony of the police officers, that Longshore was not suspected of a violent crime and that he did not exhibit violent behavior.
Finally, the State questions the applicability of Grier, noting that the issue of the validity of the arrest was not the paramount issue in the case. It finds Morton similarly unhelpful, noting that it is factually distinguishable. The State also points out that the Court of Special Appeals discussion of the arrest issue in Dixon was largely dicta and not central to the case.
We reject these arguments. We hold that, notwithstanding some factual differences to the case sub judice, Grier, Morton, and Dixon each provide the appropriate model for determining “when” someone is arrested.
C.
When there is a conflict in the evidence, an appellate court will give great deference to a hearing judge’s first-level factual and credibility determinations.
See, e.g., Nieves,
The proposition that a trial court’s determination of whether there is probable cause is entitled to great deference from a reviewing court was stated in
Illinois v. Gates,
“The task of the issuing magistrate is simply to make a practical, common-sense decision whether, given all the circumstances set forth in the affidavit before him, including the Veracity’ and ‘basis of knowledge’ of persons supplying hearsay information, there is a fair probability that contraband or evidence of a crime will be found in a particular place. And the duty of a reviewing court is simply to ensure that the magistrate had a ‘substantial basis for ... concluding]’ that probable cause existed.”
This Court recently repeated this standard:
“The applicable standard of review of a probable cause determination is: ‘so long as the magistrate had a substantial basis for [] concluding that a search would uncover evidence of wrongdoing, the Fourth Amendment [of the U.S. Constitution] requires no more.’ ”
Abeokuto v. State,
“Our review of the judge’s decision to issue the seаrch warrants is limited to whether there was a substantial basis for concluding that the evidence sought would be discovered in the place described in the application for the warrant____ Moreover, we generally pay great deference to a magistrate’s determination of probable cause. (Citations omitted).”
Deference to probable cause determinations, so long as there is a substantial basis for the finding, has been discussed and accepted by the Court of Special Appeals, as well. In
State v. Blackman,
“To the extent to which the suppression hearing judge was called upon to make findings of first-level fact and to assess the credibility of Officer Matthews, and others, those are *523 decisions that the suppression hearing judge is at a vantage point to make far more competently than we. Those are decisions, therefore, to which we, on appellate review, extend great deference and reverse only when they, as a matter of law, are clearly erroneous. No such problem is involved in this case.
“Once credibility has been assessed and first-level findings of fact have been made, such as who did what to whom and when, a very different issue emerges. It is a mixed question of law and fact. The issue is that of what significance shall be given to the first-level facts as found. That is a question as to which all reviewing judicial tribunals-the suppression hearing court, the trial court, and the appellate court alike-are called upon to exerсise an appellate-like discipline. At none of those levels of review will the court presume to decide, as if it were on the street, whether articulable suspicion existed. A reviewing court, at whatever level, will not second-guess that initial decision that had to be made and that then became the object of judicial scrutiny. By analogy to the review of probable cause determinations made by an officer on the street, we hold that the reviewing court, trial and appellate alike, must make the far more deferential determination of whether the officer had a substantial basis for concluding that articulable suspicion existed.”
This deference was employed in overturning a state appellate decision in
Maryland v. Pringle,
This Court reversed, holding that, absent specific facts tending to show Pringle’s knowledge, dominion, and control over the drugs, “the mere finding of cocaine in the back armrest when [Pringle] was a front seat passenger in a car driven by its owner is insufficient to establish probable cause for an arrest of possession.”
Pringle v. State,
The Supreme Court reversed. It first articulated the applicable standard for review of probable cause determinations, noting that “[p]robable cause is a fluid concept-turning on the assessment of probabilities in particular factual eontexts-not readily, or even usefully, reduced to a neat set of legal rules .... it deals with probabilities and depends on the totality of the circumstances.”
Focusing on the totality of the circumstances as existed in
Pringle,
the Supreme Court concluded that it was entirely reasonable for the fact finder to infer that any or all three passengers in the car had knowledge, dominion, and control of the drugs.
*527
Thus,
Pringle
dictates that the relevant inquiry is whether the “particular factual contexts,”
Applying
Gates
and
Pringle,
the standard of review in a probable cause determination is clear. A trial court’s probable cause determination is entitled to deference, and, if the appellate court determines that there is a substantial basis for the trial court to have concluded, as it did, that there was probable cause, the trial court’s determination will not be disturbed. If, on the other hand, the appellate court concludes that there is no such basis, then there is no probable cause.
See Swift v. State,
In the case sub judice, we hold that, necessarily, having determined that no arrest occurred when Detective *528 Edge stopped Longshore, the trial court did not have a substantial basis for determining that probable cause existed at the time that he was handcuffed. The suppression court viewed Longshore’s stop, when he was handcuffed, not as an arrest, but as a detention that only required reasonable suspicion, which was supplied, it opined, by the videotapе and the drugs, marijuana and trace amounts of cocaine, found in Carlson’s car. Probable cause, the court noted, existed once the drug dog alerted to the presence of drugs. Interestingly, and somewhat inconsistently, the suppression court also noted that the videotape alone was sufficient to establish probable cause to search the petitioner’s vehicle.
As we have seen, the Court of Special Appeals held that an arrest had occurred. The question that must be resolved is whether, in light of that holding, that court had a substantial basis to determine the existence of probable cause. The intermediate appellate court affirmed the petitioner’s conviction, but it did not do so on the ground on which the trial court relied; it did not accept the trial court’s analysis with regard to the nature o f the petitioner’s stop and detention. In fact, the Court of Special Appeals rejected the trial court’s characterization of the petitioner’s stop as a mere detention, holding, instead, that it was an arrest, for the justification of which probable cause was required to be shown.
Nevertheless, the intermediate appellate court concluded that there was probable cause to justify the arrest. 11 That *529 conclusion was supported, the intermediate appellate court explained, by the following factors, which it enumerated as informing its decision:
“1. Detective Smith received a call from a confidential source who had provided reliable drug related information in the past.
“2. The source informed the detective that he had observed and videotaped what he believed was a drug transаction involving appellant and Carlson, a man the source knew to have been involved in drug transactions.
“3. The detective observed the videotape twice and concluded, based on his experience, that in fact a drug transaction had occurred.
“4. The police observed the three men shown in the videotaped transaction meet again at a kiosk in the mall.
“5. The police found, in a subsequent stop of Carlson’s vehicle, a quantity of marijuana and a trace amount of cocaine.
“6. The police learned that appellant had prior drug arrests.
“7. During a subsequent stop of appellant’s car, appellant acted ‘extremely nervous’ when asked if he was transporting drugs.”
Not included in this list of factors, but clearly something to be taken into account in assessing probable cause, is the first of the three drug dog sniffs of the petitioner’s vehicle. That sniff, which was singularly unsuccessful, 12 occurred while the *530 petitioner’s vehicle was parked on the shopping mall parking lot and he was inside the mall with Carlson and the third man, with whom he had been seen. Aware of that drug dog sniff and its lack of results, to be sure, the Court of Special Appeals disposed of it dismissively and without significant discussion, stating simply, “the dog’s failure to alert during the first scan does not weigh too heavily in the probable cause calculus.”
The intermediate appellate court did not explain why the failed sniff did not weigh “too heavily in” its analysis. But that is the crux of the case: because it is a factor militating against a finding of probable cause, did that failure, weighed sufficiently, significantly negate or neutralize those several factors that militate in favor of such a finding.
We have held, to be sure, that “once a drug dog has alerted a trooper to the presence of illegal drugs in a vehicle, sufficient probable cause existfs] to support a warrantless search of [a vehicle].”
Wilkes v. State,
The context in which the intermediate appellate court expressed that opinion is both enlightening and significant. In
McKay,
police obtained information from a named source that one of the defendants was the source of drugs for his mother.
The court rejected both arguments. With respect to the first, applying a totality of the circumstances analysis, it concluded that the police had probable cause to search the defendant’s car.
“The suppression court heard testimony that the dog’s failure to alert was due to its being on medication. The court apparently credited that testimony, as reflected by the court’s comment that ‘sometimes you just have incompetent dogs.’ We treat that determination as fact. State v. Brooks,148 Md.App. 374 , 402,812 A.2d 342 (2002). Considered in the totality of the circumstances, the dog’s non-alert-particularly in view of the reasonable explanation for it-did *532 not negate the probable cause necessary for the search of the car.”
McKay,
While we agree that a failed dog drug sniff does not automatically negate probable cause, the trial court, although noting the findings of the drug dog, did not consider the failed sniff as negative evidence in its probable cause determination. Furthermore, it is clear that the Court of Special Appeals either did not consider the failed sniff as a factor, as McKay dictates, or weighed it insufficiently.
We do not agree with either court’s lack of cоnsideration given to the failed sniff in their probable cause determinations. The failed drug sniff is exactly the type of evidence that tends to undermine the conclusion of the presence of drugs. It is a negating factor that has a substantial impact on the determination of probable cause, and cannot be lightly *533 ignored. Moreover, the weight to be given to the dog sniff is directly related to the credibility of the dog’s abilities, which, in turn, can be inferred from the dog’s performance under the circumstances. If a dog fails to alert to the presence of drugs, and no explanation for why such a failure occurred is given, the trial court should weigh this differently than it would a failure of a drug dog to alert, accompanied by a plausible justification for the failure. Additionally, any inconsistencies between multiple alert results must be taken into consideration, under the totality of the circumstances.
The first sniff was conducted while Longshore’s car was parked in the mall lot. The dog failed to alert. The dog handler explained at trial that this was not a surprise, since “during the first scan there was no ‘air exchange’ as the windows were up, the doors closed, and the engine was not running.” During the dog’s second scan, however, where “a window was down and, just seconds before, the engine had been running,” the drug dog alerted to the rear of the vehicle just underneath the rear bumper — a false alert. This second scan contradicts the rationale given by the police for Tonya’s failed first sniff. It was only when the dog was actually let inside the vehicle that she was able to alert to the presence of drugs. These three inconsistent alerts severely undermine dog’s credibility as a reliable indicator of the presence of drugs. Thus, as a negating factor in the probable cause determination, we believe that the drug dog’s failure to alert during its first scan of Longshore’s car should have been given considerable weight in light of the other factors and circumstances.
While we agree with the holding in
McKay,
it is not wholly applicable here, as the State asserts. The drug sniffing dog in
McKay
had been treated with medication,
Given the lack of reliability of the drug dog and the other factual circumstances taken in concert, we cannot conclude that there is a substantial basis for the determination of the existence of probable cause. The police received a call from a confidential source who had provided reliable drug information in the past, and this source informed the police detective that he had observed and videotaped what he believed was a drug transaction involving appellant and Carlson, a man the source knew to have been involved in drug transactions. While the informant claimed that the tape showed Longshore and Carlson making some sort of exchange inside the vehicle, it only displayed two men getting into a car while a third person waited outside of the car. Despite the obvious lack of visual proof, the detective observed the videotape twice, and concluded, based on his experience, that a drug transaction had occurred.
In a probable cause determination, “the experience and special knowledge of police officers who are [attempting to establish probable cause] are among the facts which may be considered.”
Wood v. State,
Trace amounts of drugs were discovered in the car of one of the three men, when it was stopped by the police; that man, however, did not indicate that he had purchased the drugs from Longshore. The State emphasizes Longshore’s history of prior drug arrests. We have, however, previously cautioned, “to be satisfied based upon a person’s status [of having a prior drug arrest record], rather than an individualized
*535
assessment of the circumstances, would undermine the purpose for requiring officers to justify their reasons for searching a particular individual.”
Nieves,
What we are left with is a videotape that, although coming from a previously reliable source, reflects no drug activity, only innocuous or at worst ambiguous, behavior, occurring primarily in a public setting, trace amounts of drugs with no immediate or clear connection to Longshore, a prior criminal record, nervous behavior, and inconsistent results — she twice failed to alert to the presence of drugs — from a drug dog. While these facts may have provided an officer reasonable suspicion to conduct further investigation, they do not provide a substantial basis for a determination of probable cause, the standard by which we are bound to evaluate the validity of the petitioner’s arrest. To agree that probable cause existed at the time of the petitioner’s arrest, as the State contends, would force this Court to fill in gaps in the record, an exercise we are not permitted to do. We reverse on this point.
II.
The trial court also erred in admitting testimony that the petitioner refused to consent to a search of his vehicle. That evidence was inadmissible and it was prejudicial. The trial court abused its discretion in not granting a mistrial.
During the State’s case in chief, Detective Edge testified about the encounter with petitioner. After Detective Edge stopped the petitioner’s automobile, he asked him for consent to search the car. The following conversation took place:
[PROSECUTOR]: What, if anything, did you do when the car came to a stop?
*536 [DETECTIVE]: The patrol officer had — I had him ask him to step to the rear of his vehicle. At which time I made contact with the suspect and advised him why he was being stopped, and asked him for consent to search his vehicle.
[PROSECUTOR]: What, if anything, happened at that point?
[DETECTIVE]: He denied consent
[DEFENSE COUNSEL]: Objection.
[THE COURT:] Sustained.
At the bench, defense counsel moved for a mistrial, which the trial judge denied. The court instead gave the jury a “curative instruction,” stating as follows:
“Ladies and gentlemen, I instruct you to disregard what the Officer said with regard to the defendant’s response to the request to search the vehicle. For purposes of this proceeding that is immaterial.”
The Court of Special Appeals rejected the petitioner’s argument that the trial court had abused its discretion in denying his motion for mistrial, noting:
“[W]e see that it was a single, isolated statement; it was solicited by the State only in the sense that it was made in response to a question posed by the State, but it appears that the question was not intended to obtain the testimony given, and that the answer given was unexpected; Detective Edge was one of several witnesses; and there was a great deal of other evidence of appellant’s guilt, including the videotape of the suspected drug transaction and the fact that Carlson’s car contained drugs when stopped.”
The petitioner contends again, at this appellate level, that the trial court noted correctly that Detective Edge’s testimony that the petitioner denied consent to search his car was inadmissible, but that the court abused its discretion in refusing to grant a mistrial. He asserts that the trial court erred in denying his motion for a mistrial when the Detective testified that the petitioner refused to consent to a search of his vehicle. The petitioner argues additionally that the curative *537 instruction was insufficient to protect his right to a fair trial. We agree.
In holding that evidence of a refusal to consent to search is inаdmissible, many courts have drawn an apt analogy to United States Supreme Court cases that hold that a defendant’s assertion of the Fifth Amendment right to remain silent may not be used against him or her at trial.
See, e.g., Simmons v. State,
“Because the right to refuse entry is equally available to the innocent and the guilty, the refusal is as ‘ambiguous’ as silence which is maintained as a right under the Fifth Amendment. To allow the use of one’s refusal to consent to entry into his home without a warrant would be to impose a penalty for exercising a constitutional right. Allowing evidence of [the defendant’s] refusal to consent to a warrant-less search of his home was error.”
Id. at 495 (internal citations omitted). An individual’s assertion of the constitutional right to refuse a search of his car cannot be used as evidence of his guilt if the constitutional protection against unreasonable search and seizure is to have any meaning.
A person has a constitutional right to refuse to consent to a warrantless search of his or her automobile, and such refusal may not later be used to implicate guilt. An unfair and impermissible burden would be placed upon the assertion of a constitutional right if the State could use a refusal to a warrantless search against an individual.
See, e.g., United States v. Prescott,
The petitioner was prejudiced by the inadmissible testimony and the instruction of the court to disregard the testimony did not cure the error. The State’s argument that Detective Edge’s testimony was not solicited or expected by the State does not diminish the prejudice to petitioner. This is not a question of good faith/bad faith on the part of the State. An important issue in the case was whether petitioner had knowledge of the contraband contained within the car. The jury may have considered his refusal to consent to search as evidence of knowledge that the drugs were within the automobile. We cannot say that the error was harmless beyond a reasonable doubt.
See Dorsey v. State,
JUDGMENT OF THE COURT OF SPECIAL APPEALS REVERSED; CASE REMANDED TO THAT COURT *539 WITH INSTRUCTIONS TO REMAND TO THE CIRCUIT COURT FOR CHARLES COUNTY FOR FURTHER PROCEEDINGS CONSISTENT WITH THIS OPINION; CASE REMANDED TO THAT COURT FOR NEW TRIAL. COSTS IN THIS COURT AND IN THE COURT OF SPECIAL APPEALS TO BE PAID BY CHARLES COUNTY.
Notes
. Only trace amounts, insufficient for chemical analysis, of cocaine and marijuana were found in Carlson's car.
. A subsequent search of Longshore’s person revealed that he possessed $1,091 in cash. Longshore, at trial, offered the testimony of witnesses to explain his possession of this money.
. The Petitioner argues and, in doing sо, provides the second issue in this case, that, "[ajssuming an arrest, was probable cause lacking[?]” The State’s conditional cross-petition, in response to Longshore’s petition, strangely enough, actually forms the first issue in this case, that the Court of Special Appeals erred "in finding that the initial detention of Longshore amounted to an arrest....”
. Maryland Rule 8-131 provides, as relevant:
“(a) Generally. The issues of jurisdiction of the trial court over the subject matter and, unless waived under Rule 2-322, over a person may be raised in and decided by the appellate court whether or not raised in and decided by the trial court. Ordinarily, the appellate court will not decide any other issue unless it plainly appears by the record to have been raised in or decided by the trial court, but the Court may decide such an issue if necessary or desirable to guide the trial court or to avoid the expense and delay of another appeal.
*499 * * * *
"(c) Action Tried Without a Jury. When an action has been tried without a jury, the appellate court will review the case on both the law and the evidence. It will not set aside the judgment of the trial court on the evidence unless clearly erroneous, and will give due regard to the opportunity of the trial court to judge the credibility of the witnesses.”
. Previously, Montgomery County handled juvenile cases differently than any other jurisdictions in the State of Maryland. Maryland Code (1974, 1980 Repl.Vol., 1980 Supp.) § 3-801 of the Courts and Judicial Proceedings Article provided that in Montgomery County, juvenile matters would be tried in the District Court, while in the other twenty-two counties and Baltimore City, they would be tried in the Circuit Court. Section 3-801 read, at that time, as relevant:
"(h) Court-'Court’ means the circuit court of a county or Baltimore City sitting as the juvеnile court. In Montgomery County, it means the District Court sitting as the juvenile court.”
That changed March 1, 2002, however. See 2001 Md. Laws Ch. 414. Maryland Code (1974, 2006 Repl.Vol.) § 3 — 801(i) of the Courts and Judicial Proceedings Article now provides:
"(i) ‘Court’ means the circuit court for a county sitting as the juvenile court.”
. The intermediate appellate court relied on federal and state authorities: Un
ited States v. Jones,
. None of the cases that the State cites from federal and state jurisdictions regarding the reasonable use of physical force in a detention is applicable here, as, in each case, the suspect was suspected of being either aimed and dangerous, or a flight risk, circumstances that do not exist
sub judice. See United States v. Crittendon,
. Wе have addressed mixed questions fact and law in the administrative law context, stating:
"... [w]hen the agency decision being judicially reviewed is a mixed question of law and fact, the reviewing court applies the substantial evidence test, that is, the same standard of review it would apply to an agency factual finding.”
Charles County Dept. Of Social Services v. Vann,
. In
State v. Rucker,
Pursuant to
Berkemer,
this Court "reweighed” the facts and circumstances of the case differently than the trial court, characterizing the exchange between the respondent and the police as a request, rather than, as the trial court had found, a demand, and concluded that Rucker’s freedom of movement was not hindered in any way. Therefore, we held that there could not have been a formal arrest.
This holding did not accord the trial court finding any deference; it certainly did not address, or seek to assess "how a reasonable man ... would have understood the situation.”
Berkemer,
*526 "... because there was no actual arrest until after the recovery of the cоcaine, the question to be answered was whether the circumstances were such that a reasonable person would have felt that he or she was in custody. After, evaluating the testimony adduced at the hearing, the trial judge found that the respondent was in custody, thus either rejecting that which supported that he was not or drawing inferences from the evidence that supported the factual conclusion that the trial judge made. Put another way, the trial judge found that the officers' conduct in the parking lot exceeded the scope of an investigatory stop under Terry, and was, in actuality, a de facto arrest, thus triggering the respondent's entitlement to Miranda warnings. The trial court’s determination is entitled to deference and, in any event, should not easily be ignored.
"Although it professes to do so, the majority fails to accept the trial court's findings of fact and, in fact, views the sequence of events surrounding the respondent’s arrest quite differently than did the trial court____”
"Notwithstanding that they are never determined to be clearly erroneous, the majority all but ignores, and certainly does not apply, the facts as found by the trial court, and undoubtedly critical to its determination that the stop was tantamount to an arrest ...”
In contrast, in
Swift v. State,
This Court, in contrast, and unlike in Rucker, acknowledged that trial courts are in the best position to resolve questions of fact, while also noting that legal conclusions, such as whether a reasonable person would have felt free to leave, can be reviewed de novo, after giving due weight to the factual findings made by the trial court:
"Our review of the circuit court’s denial of a motion to suppress is based on the record created at the suppression hearing. Review of the trial court’s ruling on a motion to suppress evidence presents a mixed question of law and fact. The trial court is in the best position to resolve questions of fact and to evaluate the credibility of witnesses. An appellate court reviews the trial court's findings of fact only for clear error, giving due weight to the inferences fairly drawn by the trial court. The legal conclusions, however, are not afforded *527 deference, and are reviewed de novo. The conclusion of the trial court as to whether a seizure has occurred for Fourth Amendment purposes is a question of law, reviewed de novo by this Court.”
Acknowledging that ''[w]hether a reasonable person would have felt free to leave police presence is a highly fact-specific inquiry,” this Court, based on the factual testimony given at trial, concluded that a reasonable person would not have felt free to walk away under the circumstances.
. The trial court's analysis, as wе have seen, was on the basis of a detention and the concomitant reasonable suspicious standard. To be sure, it did opine that the video-tape, by itself, was sufficient to constitute probable cause; however, in context and logically, that determination does not pass the substantial basis test.
. In the case
sub judice,
the Court of Special Appeals relied on our holding in
Collins v. State,
“A finding of probable cause requires less evidence than is necessary to sustain a conviction, but more evidence than would merely arouse suspicion.
“Our determination of whether probable cause exists requires a nontechnical, common sense evaluation of the totality of the circumstances in a given situation in light of the facts found to be credible by the trial judge. Probable cause exists where the facts and circumstances taken as a whole would lead a reasonably cautious person to believe that a felony had been or is being committed by the person *529 arrested. Therefore, to justify a warrantless arrest the police must point to specific and articulable facts which, taken together with rational inferences from those facts, reasonably warrant the intrusion.”
. We note that there were two later drug dog sniffs, a second, of the exterior of the petitioner's vehicle, that occurred after the petitioner was stopped and placed under arrest, and the third one, of the interior of the vehicle. Because they were post-arrest, these latest drug dog *530 sniffs cannot be considered in the probable cause analysis. They do constitute, however, part of the totality of the circumstances surrounding the search. Thus, to thе extent that these sniffs may elucidate a relevant aspect of the probable cause construct, they may, and as we will see, will, be used.
. The intermediate appellate court also relied on
United States v. Jodoin,
"Although a drug detecting dog did not react when it sniffed the suitcase, the agents pointed out that, according to dog handlers, 'the dogs are not foolproof,' they ‘are less accurate on hot muggy days,’ and drug traffickers have found ways 'to mask the odors of contraband to fool detection efforts.' The dog's failure to react does not, in our view, destroy the 'probable cause’ that would otherwise exist. It is just another element to be considered by the magistrate."
Id. at 236. In Siluk, the court held that, where a drug sniffing dog in Houston, Texas, earlier had alerted to the defendant's suitcase, a subsequent failure to alert by a second dog at the Orlando airport did not neutralize the probable cause provided by the first alert, explaining:
"We do not accept the argument that the failure of the local narcotics dog to 'alert' to the luggage neutralized the probable cause flowing from the alert in Houston, where, as here, it was improbable that anyone had access to the suitcase between the time it left police surveillance in Houston and came under surveillance in Orlando. Moreover, although the officer in Houston was not known to the officer in Orlando, he provided such specific and detailed information that the Orlando officer was reasonable in his conclusion that the source of information about the defendant’s luggage was a fellow law enforcement officer whose information was truthful and reliable.”
