That first video is stupid. The recording started way too late for anyone to know why the police officer was interacting with the kid in the first place. All it shows is the kid resisting him over and over. The point where the police officer steps it up is when the kid said “This is gonna get worse for you.” That is a verbal threat that an officer will respond to. The kid is an idiot and as far as the video shows the officer was totally in the right.
That said I am not in favor of the stop and frisk laws, they are unconstitutional and should be stricken. This video proves nothing though. As for the other pictures…pigs…
