I guess the idea is that there will be enough people that will not actually see the video (or at least the part where he gets shot and goes down) and will accept "shot him in the back" as reality? Even that is fucking stupid though, if a guy is running away and firing blindly back over his shoulder I guess the cops just have to take cover and let him go.
And the bootlicker thing is odd, its one of those things that you never see anyone saying, that out of nowhere emerges from the leftwing portions of the internet and within a week or two its everywhere. They love that shit, they have done it with so many terms. This is an especially dumb one though, because I would be willing to bet that most people openly defending the police at this point not cannot be shamed out of it, and these people have literally been kissing and washing the feet of blacks the last few weeks.
