You don't know what the hell you're talking about. The reverses-course part is not the last time that's on video but but the previous time (according to testimony).

I just heard Giuliani on the radio saying something to the effect that they've been after this guy all this time, and then when there's no video, they claim he charged them. He either doesn't know there's video that shows what happened, or hasn't paid enough attention to it to see Arbery, on the right side of the truck with nobody in front of him, turn sharply to his left and charge at Travis, who had remained on the left side of the truck.
“ The man who pursued Ahmaud Arbery and recorded his fatal shooting told a responding officer that he blocked the 25-year-old Black man with his car “five times” before the young man’s alleged murder, an officer who interviewed him testified on the second day of trial.”
