delivered the opinion of the court:
The defendant, Marilyn Love, was charged with possession of a controlled substance with intent to deliver after two Chicago police officers found 16 small plastic bags of rock cocaine in her mouth. During a bench trial in the Cook County circuit court, the defendant made an oral motion to suppress the cocaine. The trial court denied the defendant’s motion and ultimately cоnvicted the defendant. The appellate court reversed the trial court’s ruling on the defendant’s suppression motion and reversed her conviction.
The issue before us is whether the police officers had probable cause to arrest and search the defendant. We reverse the appellate court and reinstate the defendant’s conviction.
BACKGROUND
At trial, Chicago рolice officer Olson was the State’s only witness. On direct examination, Officer Olson testified that on January 29, 1999, he and his partner, Officer Retner, were conducting narcotics surveillance in a residential area on Chicago’s west side. Around 1:50 a.m., Officer Olson, looking through binoculars, saw the defendant in front of an apartment building. Nearby, he saw a man approach a person on a bicyсle and give that person some currency. The person on the bicycle then directed the man toward the defendant. According to Officer Olson, the defendant then “removed an item from her mouth and handed it to that individual.” Officer Olson and his partner “approached and detained” the defendant and “asked her to spit out some objects in her mouth.” The defendant complied, and Officеr Retner recovered from the ground an object which looked like a roll of clear tape with 16 small plastic bags stuck to it. The officers believed the bags contained crack cocaine.
On cross-examination, Officer Olson testified that, during his 10-minute surveillance, the person on the bicycle circled between 25 feet and 300 feet from the defendant. Officer Olson stated that he sаw the man hand money to the person on the bicycle, but he did not see what the defendant handed to the man. Officer Olson did not stop the person on the bicycle or the man. As he approached the defendant, Officer Olson could not see what she had in her mouth. According to Officer Olson, “We asked her, I believe it was her name, and she had difficulty answering it. At that time I told her to spit out what she hаd in her mouth, and she did.” Officer Olson did not know the defendant had drugs in her mouth until she spit them out.
The defendant’s attorney then made an oral motion to suppress, asserting that the information in “the transcript” somehow conflicted with Officer Olson’s testimony. In response, the State summarized the police officers’ observations. The officers saw the man give currency to the person on the bicycle; they saw the person on the bicycle point the man toward the defendant; and they saw the defendant give the man an object out of her mouth: “Upon that they approach. Upon that they had probable cause to approach.” The trial court asked the defendant’s attorney if he wanted to present additional evidence in support of this motion; the defendant’s attornеy answered no. The court ruled:
“At some point [Officer Olson] approached the defendant *** and that while conducting in essence at that point an initial Terry stop or field interview or questioning, which is allowed and codified under the Illinois Criminal Code, *** noticed she had some difficulties answering it because something was in her mouth and asked her to spit the items out. I suppose arguably so he can сontinue on with the questioning from the temporary detention.
At that time he observed what he believed to be contraband which was recovered. The court does not believe there’s any 4th Amendment violation. So the motion to suppress evidence based upon that lack of probable cause will respectfully be denied.”
The parties stipulated that the plastic bags contаined cocaine. The defendant then testified in her own defense. Her version of the events which led to her arrest differed wildly from Officer Olson’s version. The defendant stated that a police officer grabbed her from behind and asked her some questions. According to the defendant, another officer hit her in the face and told her to open her mouth. The officer never asked her spit оut what was in her mouth; “he just told me to talk.” The defendant never saw the police officers recover anything from the ground. She asserted that she did not possess or sell drugs on January 29, 1999. In rebuttal, the State offered evidence of the defendant’s 1997 conviction for delivery of a controlled substance.
The court accepted Officer Olson’s testimony, rejected that of the defendant, and fоund her guilty. The defendant then filed a motion for a new trial, in which she reargued her motion to suppress. The trial court denied this motion, stating:
“This was not a situation where the officers approached and arbitrarily searched the defendant recovering contraband. Which might cause some concern with regard to [the] search issue. But the officers observed what they believed to be criminal activity afoot. That being the narcotics transactions and approached to do basically a Terry stop or field investigation.
And when they attempted to speak to this defendant, they were unable to because she had something in her mouth. They did not indicate that they let — that that substance was a controlled substance and ordering to be produced, even though that might have bеen reasonable based on the observations.
As far as the testimony goes, it could have been chewing gum or some other foreign substance or food or some other item in her mouth. So that for the officers to effectively carry on the field interview, in accordance with statute, case law, it was necessary that she remove what was in her mouth. It was causing her difficulty in answering the questions that were being put to her.”
The defendant appealed. The appellate court reversed the trial court’s ruling on the defendant’s motion to suppress and reversed her conviction.
We granted the State’s petition for leave to appeal. See 177 Ill. 2d R. 315(a).
ANALYSIS
Initially, we note that the defendant has filed a motion to strike portions of the State’s opening brief. The defendant charges that the State raises issues before this court regarding probable cause which it never pursued below or in its petition for leave to appeal. This motion was taken with the case.
Contrary to the defendant’s assertion, the State did discuss the issue of probable cause in its petition for leave to appeal, where it argued: “police could have arrested defendant, without defendant’s compliance to ‘spit it out,’ where the police arguably developed probable cause during the Terry stop ***.” Further, as we held in People v. Schott,
When a motion to suppress evidence involves factual determinations or credibility assessments, we will reverse the trial court’s ruling only if it is manifestly erroneous. People v. Buss,
The fourth amendment guarantees “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” U.S. Const., amend. IV; accord Ill. Const. 1970, art. I, § 6; see Fink v. Ryan,
“Viewed as a whole, the situation confronting the police officer must he so far from the ordinary that any competent officer would be expected to act quickly. The facts supporting the officer’s suspicions need not meet probable cause requirements, but they must justify more than a mere hunch. The facts should not be viewed with analytical hindsight, but instead should be considered from the perspective of a reasonable officer at the time that the situation confronted him or her.” People v. Thomas,198 Ill. 2d 103 , 110 (2001).
Arguing that Officer Olson exceeded the bounds of a Terry stop, the defendant directs us to People v. Harper,
The appellate court held that the Terry stop was improper:
“The facts known to the officers simply did not establish an articulable basis to believe that a crime had been, or was about to be, committed. The officers merely observed defendant leave a car parked near the subject premises, enter the building, remain for a short time, and leavе. The officers did not observe any transactions within the building or hear any conversations. They did not know what defendant did while inside the building. They had not received a report of any crime or suspicious activity in the vicinity. Their decision to stop defendant was based on no more than a hunch that he might be involved in drug activity.” Harper,237 Ill. App. 3d at 205-06 .
The court also held that were the stop justified, the search of the defendant’s mouth went beyond the weapons frisk permissible under Terry. Harper,
Unlike the officers in Harper, Officer Olson observed what appeared to be a drug transaction. He could have reasonably concluded that the man gave the person on the bicycle money in exchange for something illicit which the defendant pulled from her mouth. Innocent explanations are implausible: common sense dictates that the man probably did not go out at 1:50 a.m. in late January to pay for prechewed gum. Officer Olson had more than a mere hunch; he had firsthand knowledge of sufficient facts to create a reasonable suspicion that the defendant was selling drugs. Sеe State v. Desmond,
Consequently, Officer Olson could ask the defendant her name. A police officer does not violate the fourth amendment merely by approaching a рerson in public to ask questions if the person is willing to listen. See Immigration & Naturalization Service v. Delgado,
In order to make a valid, warrantless arrest, a police officer must have probable cause to arrest. Buss,
Our appellate court recently addressed whether the visible presence of a suspicious object in a detainee’s mouth provides probable cause to arrest. In People v. Bunch,
The appеllate court held that the officer’s detention of the defendant was unlawful. Bunch,
Unlike the officer in Bunch, Officer Olson had reasonable suspicion to detain the defendant. More importantly, unlike the offiсer in Bunch, Officer Olson’s suspicion rose to the level of probable cause. As we have noted, Officer Olson saw the man trade currency to the person on the bicycle for something in the defendant’s mouth. When he approached the defendant to ask her name and received a garbled response, Office Olson could have reasonably concluded, based on the totality of the circumstances, that the defendant was concealing drugs in her mouth. Reasonable suspicion ripened into probable cause to arrest, and Officer Olson’s order to the defendant was a search incident to a lawful arrest. See McCloud v. State,
CONCLUSION
For the reasons we have discussed, we reverse the judgment of the appellate court and reinstate the defendant’s conviction.
Appellate court judgment reversed; circuit court judgment affirmed.
Notes
The General Assembly has codified both the stop and frisk aspects of Terry in the Code of Criminal Procedure. See 725 ILCS 5/107 — 14 (West 1998) (“Temporary Questioning without Arrest”); 725 ILCS 5/108 — 1.01 (West 1998) (“Search During Temporary Questioning”).
