delivered the Opinion of the Court.
In this Fourth Amendment seizure case, we granted certiorari to review the court of appeals' decision in People v. Outlaw,
I.
On the evening of April 30, 1997, two Denver Police officers (the officers) were patrolling Denver's Five Points neighborhood. The officers were driving a marked patrol car and were wearing Denver Police uniforms.
At approximately 6:20 pm., the officer driving the patrol car stopped at a red light on northbound Welton Street at the Five Points intersection. 2 It was still daylight. While stopped, the officers in the patrol car observed four individuals-two men and two women-standing outside the 715 Club, a bar on 26th Avenue. The officers did not recognize any of the individuals, nor did they know how long the group had been standing outside the bar. They did not see the individuals exchange anything. The officers were approximately thirty-five to forty-five yards away from the individuals when they saw them.
The individuals noticed the patrol car and began walking east on 26th Avenue. The officers turned the patrol car east onto 26th Avenue to follow them. Crossing the westbound lane of 26th Avenue, the officer operating the patrol car drove it onto the sidewalk behind the four individuals. They continued to walk, with the patrol car following directly behind them.
The patrol car slowly followed five feet behind the group for a distance of twenty or thirty feet. Outlaw was closest to the patrol car. The officer driving the patrol car noticed that Outlaw's right hand was open but his left hand was closed in a fist. This officer concluded that Outlaw was holding something in his left hand. He navigated the patrol car back onto the street, into the westbound lane of traffic. He drove slowly eastbound in this lane, following alongside Outlaw for another ten to fifteen feet as Outlaw walked down the sidewalk. The officer then stopped the car and suramoned Out *154 law, by saying either "Can you come over to the vehicle" or "Come over to the vehicle." 3 He used a conversational tone of voice. Outlaw complied. He turned and walked to the patrol car.
As Outlaw approached the car on the driver's side, his left hand remained closed. The officer saw what appeared to be a small piece of clear plastic protruding from that hand. 4 Outlaw then made a sweeping motion with his closed hand, dropping it out of view for a moment. This hand was open and empty when it came back into the officer's view.
The police exited and secured Outiaw near the rear of the patrol car. They recovered two baggies of what they suspected to be crack cocaine on the ground near the patrol car. The district attorney charged Outlaw with one count of possession of a schedule II controlled substance (cocaine). See § 18-18-405(2)(a)(D).
Outlaw filed a motion to suppress all evidence in the case as the product of an illegal seizure of his person. He argued that the encounter was a non-consensual, investigatory stop conducted without reasonable suspi-clon. Because his stop violated the Fourth Amendment, Outlaw asserted that the trial court should have suppressed all evidence stemming from it.
The trial court ruled that the encounter was consensual; hence, not in violation of the Fourth Amendment. It alternatively ruled that the police had reasonable suspicion for the stop. Under habitual offender sentencing, Outlaw received twenty-four years in the Colorado Department of Corrections upon conviction.
The court of appeals affirmed. See Outlaw,
IL.
The United States and Colorado Constitutions protect against unreasonable searches and seizures. See U.S. Const. amends. IV, XIV; Colo. Const. art. II, § 7; People v. Garcia,
Police-citizen encounters are of three different types: (1) arrests; (2) investigatory stops; and (3) consensual encounters. Seq, e.g., People v. Cervantes-Arredondo,
*155 We first review the allocation of the burden of going forward and the burden of proof in suppression hearings. We then discuss the characteristics of consensual encounters and investigatory stops. Based upon the facts known to the police at the time of Outlaw's detention, we conclude that an impermissible seizure occurred in violation of the Fourth Amendment.
A.
Burden of Going Forward and Burden of Proof
At a suppression hearing, as the moving party, the defendant has the burden of going forward with evidence of an impermissible seizure. See People v. Jansen,
When the defendant comes forward with evidence of a seizure, the fact that police proceeded without a warrant places the burden on the prosecution to demonstrate the encounter's legality. See People v. P.E.A.,
Accordingly, if Outlaw showed sufficient facts, the burden of going forward shifted to the prosecution. See Jansen,
The police had no warrant here. We therefore focus our inquiry first on whether Outlaw put forth sufficient evidence of an illegal seizure. We defer to a trial court's findings of historical fact and will not disturb them if supported by competent evidence in the record. People v. D.F.,
B.
Consensual Encounter
In a consensual encounter, the individual voluntarily cooperates with the police and is free to leave at any time. See Cervantes-Arredondo, at 17 P.Bd at 147-148; Cascio,
Because the touchstone of the Fourth Amendment is reasonableness measured in objective terms, a court must consider the totality of the cireumstances in determining whether the police exercised force or authority to effectuate the stop, or whether the police merely sought the voluntary cooperation of a citizen through a consensual encounter. See Paynter,
*156
A totality of the circumstances analysis requires an examination of the behavior of the parties, as well as the physical, temporal, and social context of the encounter. "[What constitutes a restraint on liberty prompting a person to conclude that he is not free to 'leave' will vary, not only with the particular police conduct at issue, but also with the setting in which the conduct occurs." Cascio,
Even in the absence of physical force, we have determined that a seizure occurred where officers required a defendant to alter his direction of travel, walk back to where the officers were, and remain while police investigated him. See Paynter,
Outlaw met his initial burden of showing a seizure. The record here does not support the existence of a consensual encounter. According to the uncontested evidence, the police drove the patrol car onto the sidewalk and followed only five feet behind Outlaw and the other individuals for a distance of twenty to thirty feet. The police then pulled the car off of the sidewalk, into the wrong lane of traffic, and alongside Outlaw for another ten to fifteen feet. In all, the officers followed Outlaw at extremely close range for a distance of thirty to forty-five feet; during the entire period, the patrol car was not in a usual lane of traffic.
The officers' close pursuit of a pedestrian while in an automobile on a sidewalk is a "show of authority." Terry,
The trial court failed to evaluate the totality of the cireumstances; consequently, it did not apply the correct standard. See D.F.,
C.
Investigatory Stop
An investigatory stop is an intermediate level of police response, or limited seizure, made on facts justifying reasonable suspicion of a person having committed a crime. Garcia,
A police officer, having less than probable cause to arrest, may temporarily detain an individual for investigatory purposes if all of the following criteria exist: (1) there is reasonable suspicion that the individual has committed, or is about to commit, a crime; (2) the purpose of the detention is reasonable; and (3) the character of the detention is reasonable when considered in light of the purpose. See Garcia,
*157
A trial court must take into account the totality of the cireumstances known to police officers at the time of the intrusion, combined with any rational inferences therefrom. Garcia,
At the suppression hearing, the trial court ruled that if Outlaw's contact with the police constituted an investigatory stop, the police acted with reasonable suspicion. The trial court based its conclusion on the following facts and circumstances known to the officers at the time of the stop and presented through testimony at the suppression hearing: (1) the police had made drug arrests in the area in the past, and considered it to be a high crime area; (2) the police observed four people standing close together on the sidewalk; (8) these four people began walking away, apparently after seeing the patrol car; (4) Outlaw had his left hand closed in a fist; and (5) as Outlaw approached the patrol car, the officer driving the patrol car saw a piece of clear plastic protruding from Outlaw's closed hand.
Taking these facts as true, we hold that the trial court erred as a matter of law in finding that the police had an articulable and specific basis to believe that Outlaw was committing, had committed, or was about to commit a crime.
We have rejected the proposition that a history of past criminal activity in an area is itself sufficient to create a reasonable suspi-clon that a crime is being, has been, or will be committed. See People v. Greer,
Nor is a gathering of individuals on a public sidewalk sufficient to justify an investigatory stop. Peaceable gatherings are a hallmark of our democracy, explicitly protected in both the United States and Colorado Bill of Rights. See U.S. Const. amend. I (guaranteeing "the right of the people to peaceably assemble"); Colo. Const. art II, § 24. Furthermore, when a police officer approaches an individual in a public place and seeks to ask him questions, the individual may ignore the officer and proceed on his way. See Dawis,
Nor was Outlaw's closed hand enough to support reasonable suspicion. An individual might tighten his or her hand into a fist for a number of reasons, including fear or anger at being followed by police at extremely close range. We have previously held that a so-called "furtive gesture," standing alone, is too ambiguous to constitute the basis for an investigatory stop. People v. Thomas,
From the viewpoint of the observing police officer, an innocent move may often be mistaken for a guilty reaction. From the perspective of the person observed, the "furtive gesture" might be impelled by a variety of motives, from an unsettling feeling of being watched to an avoidance of what might be perceived as a form of harassment. Then again, a person's movement may not be a reaction to the police at all.
Id. (citations omitted). Finally, since we have already determined that Outlaw was "seized" at the moment the officers summoned him to the patrol car, and since the officers did not see anything in Outlaw's hand until after the seizure had taken place, the sight of plastic in Outlaw's fist cannot have any part in forming a reasonable, artic ulable basis for his stop.
Even though each of these facts, in and of itself, is insufficient to give rise to reasonable suspicion, the prosecution argues that, taken together, they established reasonable suspi-clon that Outlaw was committing a crime. We disagree.
*158
We compare the composite facts the trial court relied on here to those in Greer. In that case, a Colorado Springs police officer observed an area directly outside a bar known as a site for narcotic sales.
These facts, taken together, were insufficient to create reasonable suspicion to believe that the defendant was involved in a drug transaction. See id. We characterized this evidence as an "unarticulated hunch that a criminal act has occurred" that is "not sufficient to support an investigatory stop." Id. at 580-81.
The facts here provide even less support for a valid investigatory stop. As in Greer, the police officers here were patrolling a neighborhood known for drug transactions in an effort to combat the drug trade. Likewise, they observed individuals huddled together in front of a bar, known as a site for drug transactions. In both cases, the officers could not ascertain the nature of the conversation they were observing, nor did they actually see any sort of transaction take place. In contrast to this case, however, the police in Greer observed the group for a period of time and witnessed one member of the group pocket some money; here, when the police decided to follow behind Outlaw and his companions, no exchange or other suspicious activity had occurred. Reasonable suspicion was lacking in Greer on relatively stronger facts; it follows that no reasonable suspicion existed here to detain Outlaw through a show of police force.
Davis,
As in this case, the individuals in Davis were congregating in an area that was known to have a history of criminal activity. As here, the officers' primary suspicion was based on their inability to fully view the defendant's hand. Unlike here, the officers in Davis additionally knew the defendant as a gang member and drug dealer. The defendant looked directly at the officers before walking away. The contact between the officers and the defendant occurred in the dark of night rather than the daytime. While each of these differences was not sufficient in itself to create reasonable suspicion, see id. at 1468 (eye contact with officers); id. at 1469 (knowledge of prior criminal record), together 7they might have led the court to a conclusion that officers had reasonable suspicion. Nonetheless, the court found that reasonable suspicion did not exist. Id. at 1468. It follows, based on the facts known to the officers in this case, which are weaker than those in Davis, that there was no reasonable, articulable suspicion of a crime here.
*159
Finally, we contrast our decision in Ar-chuleta,
Here, Outlaw neither ran upon seeing the officers nor sought to evade them. He did not attempt to hide from the officers. Instead, he maintained a steady walking pace as the patrol car followed him from behind. A hallmark of a consensual encounter is that a citizen is free to ignore police attempts to inquire about the citizen's activity. Surely, then, a citizen should be able to proceed on his way at a normal pace despite the choice of officers, who lack reasonable suspicion of a crime, to follow him in a patrol car. Outlaw's conduct in ignoring the officers and continuing to walk away failed to contribute to a valid basis for reasonable suspicion.
Taken in their totality, the uncontroverted facts here demonstrate that Outlaw's encounter with the police was not consensual. It was an investigatory stop not based on reasonable suspicion. We therefore hold that Outlaw suffered an unconstitutional seizure. The trial court should have suppressed evidence deriving from the seizure.
IIL.
Accordingly, we reverse the judgment of the court of appeals. We return this case to the court of appeals with instructions to remand it to the trial court for further proceedings consistent with this opinion.
Notes
. We granted certiorari on the following issue: Whether the court of appeals erred in stating that the defendant "hafs) the burden of proving by a preponderance of the evidence whether and when a 'seizure' {of his person] occurred."
. This intersection marks the convergence of Welton Street, Washington Street, 27th Street, and East 26th Avenue in central Denver.
. The officer could not state with certainty whether his statement to Outlaw took the form of a question or a command.
. The officer offered conflicting testimony concerning exactly what he saw in Outlaw's closed hand. At the preliminary hearing, he gave no testimony about seeing plastic in Outlaw's hand. At the Motions hearing, he stated that the clear plastic protruded from between Outlaw's thumb and index finger. At trial, he stated that the clear plastic protruded from near Outlaw's pinky finger.
. Both parties fully briefed the issue of whether the contact between Outlaw and the officers was a consensual encounter, as well as the issue of whether the contact was a valid investigatory stop supported by reasonable suspicion. We therefore address these closely intertwined issues. Where the evidence in the record is un-controverted, we apply the correct legal test in deciding the case. See, e.g., People v. Newton,
