If you pay attention to the order of events - He had the "Red shirt mask" on before being shot. As he was chasing the kid he was in "incognito mode." On first viewing I thought the shirt wrap was to try and treat the wound, but if you re-watch and pay attention he is shirtless chasing the kid. The shirt - his impromptu mask. It can demonstrate the intent to conceal identity at that point. Could speak to intent to do something illegal. It was not a Covid thing as earlier in the evening he was mask free/didn't care "Shoot me nigga, shoot me nigga" clip.
