After a bench trial, appellant Terrance Crossland was found guilty of two counts of assault on a police officer (“APO”), in violation of D.C.Code § 22-405(b) (2001). On appeal, he challenges the sufficiency of the evidence. He also asserts that the trial court erred in denying his post-trial motion for a judgment of acquittal, which he sought as a sanction against the government for the police officers’ violation of his Fourth Amendment rights. We affirm.
I.
The government presented evidence that on the evening of April 24, 2010, Metropolitan Police Department (“MPD”) Officers Brandon Baldwin and Kim McCue were engaged in an “aggressive high visibility patrol” in the area of Third and Bryant Streets, N.E. The officers, who were in full uniform, stopped appellant and his cousin Joseph Womack, both of whom were standing near the corner, as part of their effort to gather information about a rash of recent shootings and drug sales in the area. Officer Baldwin acknowledged that neither man was “doing anything unlawful” when the officers stopped them. The officers instructed both men to place their hands on a nearby fence for a weapons pat-down. Appellant “initially” com*1007plied, but quickly became “agitated,” telling Officer Baldwin words to the effect of “Fuck this shit. I’m tired of this.” Appellant then “delivered [an] elbow strike” to the officer’s head. Next, appellant “got into a fighting stance,” holding both fists in front of his face, and attempted to “deliver another strike with his fist,” but Officer Baldwin “deflected th[e] blow” and hit appellant. Officer McCue jumped on appellant’s back and delivered a “couple of knee strikes” to “take [appellant] to the ground.” As appellant struggled with Officer McCue, Officer Baldwin sprayed appellant’s face with pepper spray. The officers then attempted to handcuff appellant as he lay on his stomach on the ground. After they put handcuffs on one of his hands, appellant flailed the handcuffed arm about while tightening the muscles in his other arm to keep the officers from removing it from underneath his body. Officer Daniel Castan arrived after one of the other officers signaled for assistance. Over his radio, Officer Castan had been able to hear Officer Baldwin saying, “Stop resisting, stop resisting.” With Officer Castan’s help, the three officers eventually were able to place appellant in handcuffs.
Appellant testified that he did not elbow or try to hit Officer Baldwin. Rather, appellant testified, the officer tried to throw him to the ground and then punched him in the eye when, instead of immediately sitting down as the officer instructed him to do after the pat-down, appellant asked whether he could pull up his pants. Appellant claimed that he was already sitting down when the officer “maced” him, and that thereafter he held his arms “straight out,” allowing the officers to handcuff him. The defense also called several other witnesses who claimed to have seen the officer hit appellant without provocation or described appellant’s reputation for peacefulness.
The trial court found that appellant was guilty of APO against Officer Baldwin in that he elbowed the officer in the head, punched at the officer, and resisted the officer’s efforts to arrest him. The court found appellant guilty of APO as to Officer McCue “based on his ... resisting her attempts to put him under arrest.” The court specifically credited Officer Baldwin’s testimony, noting that it was corroborated by the testimony of Officer Castan. The court explained that it did not credit appellant’s testimony or that of the witnesses he called because “[a]lmost all of them had a bias” and because it was “not credible ... that the police were out that day, randomly beating people up for no reason” and that even if they were doing that, it made no sense “that they would beat up [appellant], as opposed to Mr. Wo[ ]mack, whom they had a history with” and had arrested the week before. The court agreed that “the police did not have any right to go up and start searching” appellant and Womack when “they were not doing anything wrong or illegal at that point,” but cited the law in this jurisdiction that “even if the police are wrongfully searching you or arresting you, the subject does not have the right ... to respond by physically resisting or assaulting the police.”
II.
Appellant argues that the evidence was not sufficient to establish that he “purposefully hit the officer with his elbow rather than through accident or mistake.”1 He also contends that the evidence did not support his APO convictions *1008because he was entitled to defend himself against the officers’ use of excessive force. As the trial judge recognized, however, this case “really ... c[a]me down to a question of credibility” of the witnesses, and the trial court’s credibility determinations are “well nigh unassailable.” McCraney v. United States, 983 A.2d 1041, 1061 (D.C.2009). The trial court specifically credited Officer Baldwin’s testimony, which was to the effect that appellant “delivered the elbow strike” and attempted to hit the officer while in a “fighting stance” (ie., that appellant’s assaultive conduct toward the officer was intentional); that appellant did so without the officer having used any force against appellant; and that Officer McCue jumped on appellant’s back and struck his knees only after appellant had attempted to hit Officer Baldwin. The court also credited Officer Baldwin’s testimony that appellant resisted Officer Baldwin’s and Officer McCue’s efforts to handcuff him.2 As appellant has not “established that the trial court’s findings are plainly wrong or without evidence to support them,” Vaas v. United States, 852 A.2d 44, 46 (D.C.2004) (citation and internal quotation marks omitted), we are satisfied that the evidence was sufficient to permit the trial court to find beyond a reasonable doubt that appellant was guilty of APO as to each of the officers.
III.
In his post-trial Motion for Judgment of Acquittal, appellant argued that “because Officer Baldwin’s behavior violated his [Fourth Amendment] rights,” the trial court “should consider sanctioning the Government” by entering a judgment of acquittal. Relying on Mapp v. Ohio,3 appellant argues that the trial court erred in denying his motion, contending that “the only way to deter the MPD police policy of ‘aggressive high visibility patrol,’ ... is to remove the incentive” for police officers to disregard constitutional rights. We discern no reason to doubt (and the government does not dispute) that Officer Baldwin’s conduct — forcibly searching appellant when, as the officer acknowledged, appellant was doing nothing unlawful — violated appellant’s Fourth Amendment right to be free from unreasonable searches and seizures. However, application of the sanction established by Mapp (the so-called “exclusionary rule”) has “been limited to cases in which the prosecution seeks to use the fruits of an illegal search or seizure against the victim of police misconduct.” Artis v. United States, 802 A.2d 959, 967 (D.C.2002) (quoting United States v. Leon, 468 U.S. 897, 910, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984)). This case did not involve the seizure of evidence, and the authority that appellant cited did not require or authorize the trial court to grant appellant’s request for a judgment of acquittal. Moreover, as the trial court recognized, the APO statute “prohibits forceful resistance even if the officer’s conduct is unlawful.” Dolson v. United States, 948 *1009A.2d 1193, 1202 (D.C.2008) (explaining that the rationale for this rule is to “deesealate the potential for violence which exists whenever a police officer encounters an individual in the line of duty”) (citations and internal quotation marks omitted). The trial court did not err in denying appellant’s motion.
Wherefore, the judgment of the trial court is
Affirmed.
. In assessing evidentiary insufficiency, we "view the evidence in the light most favorable to the government, giving full play to the right of the [trial judge] to determine credibility, weigh the evidence, and draw justifiable inferences of fact.” E.g., Ball v. United States, 26 A.3d 764, 768 (D.C.2011) (citation and inter*1008nal quotation marks omitted). "To prevail, appellant must show that the government presented no evidence upon which a reasonable mind could find guilt beyond a reasonable doubt.” Watson v. United States, 979 A.2d 1254, 1256 (D.C.2009) (citations and internal quotation marks omitted).
. Contrary to appellant's suggestion, nothing in the court's findings suggests that the court deemed appellant’s having put his hands up to his eyes in reaction to the pepper spray to be the action by which appellant resisted arrest. The court relied instead on the testimony that appellant "struggl[ed] on the ground” and "ke[pt] one hand under his body” as the officers tried to get him in handcuffs.
. 367 U.S. 643, 655, 81 S.Ct. 1684, 6 L.Ed.2d 1081 (1961) ("[A]ll evidence obtained by searches and seizures in violation of the Constitution is, by that same authority, inadmissible in a state court.”).
