A jury found Johnson guilty of murder of a law enforcement officer while armed, aggravated first-degree murder while armed, and related other offenses, all stemming from the shooting death of Metro Transit Police Officer Marlon Morales while on duty inside the U Street Metro station in Northwest D.C. on June 10, 2001. In these consolidated appeals, Johnson challenges, on Fourth Amendment grounds, the denial of his motion to suppress Officer Morales’ service weapon (and his statements relating thereto), which police seized from Johnson during a traffic stop and frisk in Philadelphia four days after Morales was shot. He also contests the trial court’s denial of his motion for a new trial based on newly discovered evidence in the form of an alleged recantation by a government witness. We hold that the trial court correctly analyzed the evidence and the law relating to the seizure and that the suppression motion was properly denied because the Philadelphia police acquired articulable reason to suspect that Johnson might be armed and pose a danger to their safety before the frisk occurred. Because we also find that the court did not erroneously exercise its discretion in denying the motion for a new trial, we affirm.
I.
A.
At the suppression hearing, the government presented the testimony of two Phil*364adelphia police officers, Michael Harvey and Lisa Heil. While on motor patrol in Northwest Philadelphia, Officer Harvey observed Johnson driving an Oldsmobile with an expired inspection sticker. Using the overhead lights and siren on his marked police car, Officer Harvey signaled to the driver to stop, but saw that he appeared reluctant to comply and was “very nervous,” looking “to his left, his right” and “over his shoulders,” not “like he was going to stop.” When two other police cars pulled into the street ahead of Johnson, however, he stopped the Oldsmobile and opened the driver’s door. Officer Harvey ordered him to close the door and stay in the car, then approached and asked for his driver’s license and registration. Johnson retrieved a registration from the glove box but stated that “he did not have a driver’s license, that he was out running an errand to pick up diapers for ... his baby’s mother.” He appeared “hyper” to Officer Harvey, “moving around a lot in the vehicle” and saying that “he was on his way home from getting diapers and ... had to get these diapers home.” Officer Harvey “saw no diapers within the vehicle.” He radioed a stop report to the police dispatcher describing the car and tag number. While doing so he noticed Johnson again open the car door to exit, and he again ordered him to stay inside the vehicle.
At that point two backup officers, including Officer Heil, arrived on the scene, and simultaneously a report came over the police radio stating that the car was in a “try and locate status.” Officers Harvey and Heil both testified what this meant and required of them under Philadelphia police practice. According to Officer Harvey, a “try and locate” vehicle is one that has been:
taken by somebody that the owner knows. It’s not necessarily a stolen vehicle, but it’s taken by someone that the owner knows and the owner wants the vehicle back. After so many days, the vehicle’s supposed to be put in the system as stolen, but due to the volume of cars that are in “try and locate” status, a lot of times they’re not updated as stolen cars.
Once a car is known to be in this status, Officer Harvey explained, the police “remove the driver from the vehicle and recover the vehicle for the owner.... We attempt to either contact the owner and have them pick it up at the location, or we have the vehicle towed to a secure location and then the owner can pick [it] up from there.” When a car is in the “try and locate” status, Officer Harvey continued, both the car and the driver “get[ ] investigated.” “[A]s far as vehicle investigations ... you ... run the tags, confirm valid registration, whether the car is in stolen status or not whether it’s a felony vehicle.... [A]lso, the operator. You have to make sure there’s no [‘]wants[’] and that he has a good license.” The need to investigate the driver was heightened, Officer Harvey added, “because of the totality of all the circumstances,” the fact that he “didn’t have an ID on him,” his suspicious statement about the diapers, and “his movements throughout the ... car stop.” Thus, when the report came back on the “try and locate” status of the car, Officer Harvey decided that he needed to clarify “who [Johnson] was at that point ... [a]nd until I was able to run him, either through BMV [Bureau of Motor Vehicles] to find out if he had a license or whatever or an ID card,” he was going to be detained on the scene.1 Officer Heil’s similar under*365standing was that, given the combination of the “try and locate” report — a status akin to but not the same as “reporting [the vehicle] stolen” — and Johnson’s failure to have a driver’s license or “proof of who he [was],” the police were authorized to “detain him and even take him in for investigation.”
The officers therefore ordered Johnson out of the car and attempted to position him against the rear of the Oldsmobile to create some space between the vehicle and the front of Johnson’s body to be able to pat him down. Shortly thereafter, however, Johnson resisted placing his hands against the car and moved one of them down to his waist or thigh area, an action he immediately repeated. Attempting to restrain him, Officer Harvey looked down and saw that Johnson was grabbing the handle of a gun sticking out of his left pant leg. After an intense struggle involving Johnson and the three police officers (as well as an off duty officer who fortuitously arrived on the scene), the officers seized the gun, subdued and arrested Johnson.
B.
Based upon these facts, Judge Keary found that, although Johnson had been stopped for a traffic violation, the circumstances gave them reason to suspect that his involvement with the Oldsmobile was criminal in nature and that he might be armed. Crediting Officer Harvey’s testimony in particular, she found that when the car was reported missing and in the “try and locate” status, he had reason to suspect that “the car m[ight] be stolen,” and thus that further detention of Johnson on the scene would be necessary:
[I]n such a scenario, [the judge found,] the record reflects that a driver must be investigated. He cannot leave the scene.... [I]n Mr. Johnson’s case, the police ... had very little information on him.... [T]hey know he has no license, no identification to reflect a name. Clearly, they have grounds to detain him further to conduct some limited investigation.
And, Judge Keary reasoned, this need for continued immediate contact with Johnson during the investigation prompted a reasonable concern for the officer’s safety, given Johnson’s entire behavior:
First, [Johnson] was hesitant about pulling over, initially, and did not immediately pull over in response to the sirens and the lights.
Second, [Johnson] was looking around, behind and to the side of him, and showed signs of nervousness or hypervi-gilance.
Third, [Johnson] tried to exit his vehicle while Officer Harvey was still inside his, having just stopped; and had to be told by Officer Harvey not to get out, and to stay in the car, with the door closed.
Fourth, having been told once not to get out of the car, [Johnson] later tried again to exit the vehicle, and had to again be told to stay in the car; factors which the officer certainly found suspicious and of concern....
Fifth, when Officer Harvey talks to [Johnson], [Johnson] gives a name which is false — although Officer Harvey certainly does not know that at that point— and seems somewhat nervous, and like he did not want to be detained for very long, and did not wish to be delayed.
Sixth, [Johnson] had no license.
Seventh, [Johnson] gave an explanation of being on his way home from an errand to get diapers, but Officer Harvey saw none in the car.
*366Eighth, Officer Harvey describes [Johnson] as being hyper, and moving around a lot in the vehicle.
And lastly, the vehicle is reported to be in “tried to locate” status, which means that the car may be stolen[.]
Judge Keary then listed the following factors as justifying the officer’s frisk due to safety concerns:
[Johnson] is behaving in a suspicious fashion: First, having not immediately stopped his vehicle in response to the police sirens; then two times having tried to exit the vehicle, even after having been told once not to; also driving without a license; also saying that he has bought diapers when none can be seen in the car; and then having in his possession a vehicle which has apparently been taken without permission, or without continued permission to have the vehicle.
Lastly, [Johnson] is noted to be very nervous, hyper, and moving around a lot in the vehicle.
When this person is taken out of the car ... by Officer Harvey, and is just a couple of feet away from the officer, face-to-face, it is clearly reasonable for Officer Harvey to fear for his safety.... While there are two other officers there, he is the only one close to [Johnson]; and he is actually very physically close to [Johnson], None of the others, including Officer Harvey, has their weapons drawn, or is in any other way prepared to intervene if [Johnson] should pull a weapon, or do anything else of a physically-aggressive nature.

I conclude, on the basis of the totality of circumstances here, as testified by the witnesses, that a frisk was warranted for the officers’ protection.
II.
We begin our discussion with what is not at issue on this appeal. Johnson does not dispute that the police had reason to stop his car and order him to step out of it. See Pennsylvania v. Mimms, 434 U.S. 106, 98 S.Ct. 330, 54 L.Ed.2d 331 (1977) (per curiam) (holding that where a police officer observes expired automobile tags, it is reasonable and comports with the Fourth Amendment for the officer to order the driver out of the car, even absent a suspicion of foul play). Nor does he question their authority to detain him at the scene for some appreciable length of time while they clarified his relation to the car and, indeed, determined who he was (because he had no driver’s license or other written identification). Further, he concedes that once he disobeyed the order to keep his hands on the car and instead (twice) moved his hand down to his waist or upper-thigh area, the police had an objectively reasonable suspicion that he might be reaching for a weapon and could frisk his person.
It is what took place in-between — between the stop and Johnson’s threatening downward movement — that divides the parties. Johnson argues that nothing the police observed before they laid hands on him and ordered him to “assume the position” against the car justified the intrusion of a patdown or frisk (we hereafter use the two words interchangeably). The government, for its part, poses the initial question of whether a frisk had even begun before Johnson made the tell-tale movement of his hand toward his waist and undeniably invited a further search. The government argues that there is no justification for treating a mere decision by the police to frisk, even followed by a verbal order to the suspect to assume the frisk position, as the commencement of the actual patdown.
*367One can cogently argue that it makes little conceptual sense to regard a frisk— by definition the physical act of running one’s hands over a person’s body — as having begun before the police begin to pat down the exterior of a person’s body. See People v. Batista, 88 N.Y.2d 650, 649 N.Y.S.2d 356, 672 N.E.2d 581, 583 (1996) (defining a “frisk” as a “pat down of the outer clothing of a suspect”); Or.Rev.Stat. § 131.605(3) (2011) (defining frisk as “an external patting of a person’s outer clothing.”). See also Webster’s Third New International Dictionary 912 (2002) (defining “frisk” to mean “to search or go through ... for concealed weapons or stolen articles ... by running the hand rapidly over the clothing and through the pockets”). Indeed, one may ask whether taking hold of a person by the elbow or shoulder to move him into a better position for a frisk is functionally — or legally — part of the patdown itself, rather than of the antecedent detention leading to a frisk. See Graham v. Connor, 490 U.S. 386, 396, 109 S.Ct. 1865, 104 L.Ed.2d 443 (1989) (“[T]he right to make an ... investigatory stop necessarily carries with it the right to use some degree of physical coercion....”); United States v. Sokolow, 490 U.S. 1, 7, 109 S.Ct. 1581, 104 L.Ed.2d 1 (1989) (investigatory stop upheld although officer physically grabbed defendant and moved him to sidewalk).
Both parties correctly conceded at oral argument that the question of “when a frisk commences” is a question of law. See United States v. Santos, 403 F.3d 1120, 1124-25 (10th Cir.2005) (analyzing extensively the standard of review that applies to various types of findings made by trial court at a suppression hearing); Jackson v. United States, 805 A.2d 979, 983-85 (D.C.2002) (when “seizure” occurs is a question of law). Counsel for Johnson urged at oral argument that as a matter of law, the frisk commenced in this case when he was ordered to “assume the position” against the car. She stated that this result was mandated by our decisions in James v. United States, 829 A.2d 963 (D.C.2003); Jackson, 805 A.2d at 979; and Powell v. United States, 649 A.2d 1082 (D.C.1994); These cases do not support her claim.2 We need not further explore (or decide) this issue to resolve this appeal, however, because we conclude that the evidence and the law support Judge Keary’s ruling that when Officer Harvey ordered Johnson to assume the position for the body frisk, the officer reasonably suspected that he might be armed and a danger to his safety, hence justifying the patdown.
Our measure of review in this area is well understood. While this court reviews de novo the trial court’s conclusion that reasonable grounds for a frisk existed, we must view “the facts and all reasonable inferences therefrom ... in favor of sustaining the trial court’s ruling.” Singleton v. United States, 998 A.2d 295, 299 (D.C.2010). Because a frisk of a person is “an intermediate response,” Adams v. Williams, 407 U.S. 143, 145-46, 92 S.Ct. 1921, 32 L.Ed.2d 612 (1972) (stating that intermediate responses, such as “limited protective search[es] for concealed weapons,” are permissible under Terry during *368the course of a “reasonable investigatory stop[s]”), between contact with a citizen that entails no Fourth Amendment seizure and “the full field-type search” permitted incident to a valid arrest, Knowles v. Iowa, 525 U.S. 113, 118, 119 S.Ct. 484, 142 L.Ed.2d 492 (1998), only reason to suspect that the person may be armed — not reason to believe he is armed — is necessary to justify the frisk. See generally Arizona v. Johnson, 555 U.S. 323, 129 S.Ct. 781, 172 L.Ed.2d 694 (2009) (“[A] driver, once outside the stopped vehicle, may be patted down for weapons if the officer reasonably concludes that the driver ‘might be armed and presently dangerous.’ ”); see also James v. United States, 829 A.2d 963, 966 (D.C.2003) (“An articulable suspicion is ‘substantially less than probable cause’.... ”); Gomez v. United States, 597 A.2d 884, 888 (D.C.1991) (“The requirement of ‘articulable suspicion’ is not an onerous one.”).
We are mindful that when considering whether the totality of the circumstances gives rise to an articulable suspicion, we do so “through the eyes of a reasonable and cautious police officer on the scene, guided by his experience and training.” Singleton, 998 A.2d at 300 (quoting (Antonio) Green v. United States, 662 A.2d 1388, 1390 (D.C.1995)). Moreover, the issue is not whether Officer Harvey himself subjectively harbored a suspicion that Johnson was armed, but whether a reasonable officer in the circumstances would have harbored such a suspicion. See Whren v. United States, 517 U.S. 806, 813, 116 S.Ct. 1769, 135 L.Ed.2d 89 (1996) (“[T]he fact that the officer does not have the state of mind which is hypothecated by the reasons which provide the legal justification for the officer’s action does not invalidate the action taken as long as the circumstances, viewed objectively, justify that action.”) (quoting Scott v. United States, 436 U.S. 128, 136, 138, 98 S.Ct. 1717, 56 L.Ed.2d 168 (1978)) (internal quotations omitted).
As Judge Keary found, even before the police acquired reason to suspect that Johnson’s possession of the Oldsmobile might be criminal, his actions and the situation had put the officers on guard. During the police pursuit Johnson seemed reluctant to stop his car and appeared “hyper”-nervous. Once he stopped the car, he twice tried to step out of it despite orders to remain inside. Further, he had no license to drive a motor vehicle and, seemingly to excuse that fact, told the police that he was en route home from an emergency trip to buy diapers, a fact of which the police saw no visible evidence in the car.
We need not determine whether, at this point, the constitutional strictures of Terry and its progeny had been satisfied,3 for *369then the police learned of the “try and locate” status of the Oldsmobile. Judge Keary found that Johnson was driving a vehicle without the owner’s present permission, and that the vehicle was possibly even stolen, and the record supports that finding. After an indefinite number of days, according to Officer Harvey, a car designated “try and locate” is to be regarded — “put in the system” — as stolen, although police records often failed to be updated to reflect that change. Consequently, while the officers had no reason to believe that Johnson was engaged in more than the unauthorized use of a motor vehicle, a misdemeanor under Pennsylvania law4 for which they did not intend to arrest him, they had reason to suspect that his possession was felonious.5 This, together with the circumstances described above, cast a different and potentially more dangerous light on what was the further — and potentially lengthy — need for the police to keep him in their presence while they investigated his identity and connection with the car.
The police, in short, were not obliged to take the risk that a person potentially subject to arrest for felony theft had on his person the means — a weapon — of preventing his apprehension for a serious crime. See United States v. Murphy, 261 F.3d at 743 (finding frisk of driver permissible where police knew the driver was not the owner of an out-of-area car — he was a male, while the car registrant was a female — and he had no driver’s license, meaning that the officer “had no way to determine the identity of the person with whom he was dealing and whether [the person] was a criminal and might be dangerous.”); Powell, 649 A.2d at 1090-91 n. 5 (Farrell, J., concurring) (distinguishing the lead opinion in Powell, where the police had observed only an “ambiguous movement” and nervousness on the part of a person stopped for a traffic violation, from a hypothetical case where the person was suspected of a more serious offense, in that his actions “bespoke someone, for example, engaged in possession of a stolen vehicle”).6 See also State v. Cowart, 862 So.2d 225, 231-32 (La.Ct.App.2003) (concluding that police reasonably believed a suspect may be armed during a traffic stop for driving with an expired inspection sticker because the suspect “was pacing back and forth” and “failed to produce a driver’s license or identification”).7
We agree with the view expressed by the Court of Appeals of New York in People v. Rivera, 14 N.Y.2d 441, 252 N.Y.S.2d 458, 201 N.E.2d 32, 35 (1964) and *370quoted by the court in Batista, 649 N.Y.S.2d 356, 672 N.E.2d at 583:
If we recognize the authority of the police to stop a person and inquire concerning unusual street events we are required to recognize the hazards involved in this kind of public duty. The answer to the question propounded by the policeman may be a bullet; in any case the exposure to danger could be very great. We think the frisk is a reasonable and constitutionally permissible precaution to minimize that danger.
Viewing the concatenation of circumstances in their totality, as we must, Singleton, 998 A.2d at 300, and “through the eyes of a reasonable and cautious police officer on the scene, guided by his experience and training,” id., we agree with Judge Keary that the police had “more than a mere ‘hunch’ or ‘gut feeling” ” that Johnson might be armed, James, 829 A.2d at 966, and were justified in adopting the “intermediate response,” Adams, 407 U.S. at 145-46, 92 S.Ct. 1921, of patting him down while they sought to dispel their reasonable suspicion that he might be in possession of a stolen car. We hold that Judge Keary correctly denied the motion to suppress for the reasons she stated.
III.
Johnson argues separately that the trial judge erroneously denied his motion for a new trial based on recantation by a trial witness against him, Ethan Means. The judge denied the motion because, in her view, Means’s post-trial statements did not contradict his trial testimony and, in any event, she did not credit his post-trial statements. Johnson argues that the judge failed to appreciate the significance of Means’s purported recantation, i.e., that while Means did not specifically renounce the truth of his prior identification of Johnson as the shooter in a related crime,8 Means did recant as to the certainty of his identification. We find no abuse of discretion in the judge’s denial of the motion.
A.
To understand the issue, we must first summarize briefly Means’s role as a witness against Johnson. According to the government’s proof, on the day Johnson shot and killed Officer Morales, he traveled to Philadelphia, and four days before the police arrested him there in possession of Morales’s service revolver, he shot and wounded Means using the same gun he had used to kill Morales. According to Means’s trial testimony, he and a friend, Reynolds, had been planning to spend the evening of June 6, 2001, selling drugs from an apartment Reynolds rented. They bought some food, and on their way back to the apartment were approached by Johnson, who offered to exchange five dollars for a ride. Reynolds agreed, and Johnson went to Reynolds’s apartment with Reynolds and Means. After ten minutes in the apartment, Johnson left, after which Reynolds too left, leaving Means alone in the apartment.
Twenty minutes later, Means heard a knock at the door. When he opened the door, Johnson appeared, forced him into the apartment, and shot him in the face. After taking Means’s money, Johnson left, and Means escaped to find help. After being released from the hospital, he told Reynolds that Johnson, the man they had picked up that evening, was the one who shot him. Both Means and Reynolds later identified Johnson in a photo lineup as the man to whom they gave a ride on June 6th. Both men also identified Johnson in *371court, where Means specifically identified him as the man who shot him in the face.
Following his conviction in the present case, Johnson was tried in Pennsylvania for attempting to kill Means. The Commonwealth did not call Means as a witness, and Johnson was thereafter acquitted. Johnson thereafter filed a motion for a new trial in the District of Columbia, contending that, at his preliminary hearing in Pennsylvania, Means recanted his trial testimony and this “recantation” constituted newly discovered evidence that probably would produce an acquittal in a new trial. The government argued that Means did not recant but, instead, merely attested to a present failure of memory that, in any event, was not credible.
Judge Keary rejected Johnson’s request for a new trial. After comparing Means’s District of Columbia trial testimony with his Pennsylvania-hearing testimony, she ruled that Means had not recanted his trial testimony and, in any event, that his post-trial statements were not credible “when examined within the totality of the circumstances surrounding his testimony.”
This court reviews a decision to deny a new trial based on newly discovered evidence for abuse of discretion. Herbin v. United States, 683 A.2d 437, 442 (D.C.1996) (citation omitted); Johnson v. United States, 398 A.2d 354 (D.C.1979). Where the denial is reasonable and supported by the record, reversal is not warranted. Herbin, 683 A.2d at 442. Where the motion is based on the recantation of a witness, “the trial court first determines the credibility of the recantation and that witness’s trial testimony.” Id. 441 (citation omitted). “If the trial court determines that the recantation is not credible, that determination ends the inquiry.” Id.
Johnson’s argument that Means recanted the certainty of his identification rests on the predicate that his preliminary hearing testimony in Philadelphia was truthful and credible. The trial judge, however, was not bound to credit Means’s preliminary hearing testimony, and she expressly chose not to do so. Rather than finding that testimony credible, she rejected it as contrary to what she found to be his truthful trial testimony in the present case. This determination was well within her authority. “Recanting affidavits and witnesses are looked upon with the ‘utmost suspicion..'" United States v. Kearney, 220 U.S.App. D.C. 379, 384, 682 F.2d 214, 219 (1982) (citation omitted); accord Godfrey v. United States, 454 A.2d 293, 300 n. 26 (D.C.1982). The judge discredited Means’s recantation because it was equivocal, if not wholly evasive, especially when compared to his detailed and thorough trial testimony, which had been thoroughly tested on cross-examination. Means’s trial testimony was also corroborated by Reynolds, who testified at the Philadelphia trial consistently with his testimony in this case. The judge’s reasoning was “persuasive and supported by the record,” Bell v. United States, 871 A.2d 1199, 1201 (D.C.2005), and she was well-positioned to assess the credibility of a recantation based on the affidavit and trial record without holding a hearing. In short, her finding that Means’s recantation was not credible “ends the inquiry.” Herbin, 683 A.2d at 441.
Affirmed.
. Officer Harvey’s answer just quoted was in response to defense counsel's question: "And when you had learned about the ‘try and locate' status you were going to just hold Mr. *365Johnson until the owner of the car came on the scene”?
. James deals with the issue of whether or not there was a constitutionally valid basis for the search of an automobile incident to a Terry stop, Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), not the frisk of a person. Jackson deals with the issue of when a seizure occurred pursuant to Terry, not when a frisk commenced. And Powell deals with whether reasonable grounds under Terry existed for the frisk, not when the frisk commenced. Our research discloses no decision of this court deciding the question of “when a frisk commences.”

Murphy, 261 F.3d 741, 743 (8th Cir.2001) (stating that a search is proper where the collective circumstances, such as a lack of identification and out-of-state license plates, "amount to unusual conduct” in the eyes of a reasonable officer, giving rise to the belief that the individual "might have been engaged in a crime and might pose a danger to a law enforcement officer's safety”); James, 829 A.2d at 966 ("[A]ppellant’s [furtive] movements, when considered together with his failure to stop immediately, the nature of the neighborhood as a high crime area, and [the officer's] experience, raised a reasonable suspicion in the officer’s mind that appellant had a gun.”); with Powell, 649 A.2d at 1089 ("[A] routine traffic violation, coupled with a slight hesitance on the part of the motorist does not establish reasonable suspicion that a person is armed and dangerous.”).
