Cops can get away with murder by claiming it was self-defense under certain circumstances. So they engineer those circumstances so they can kill.
For example, their training teaches them that a man with a knife can kill them faster than they can draw their gun if he is within 20 feet. So the cop comes within 10 feet of the man in this video specifically so he can claim "well, he was within 20 feet so he was a threat." He could have shot him from 50 feet away, but then he wouldn't have had an excuse.
Other examples I've seen: A cop will step in front of a moving car so he can claim that the car was going to run him over if he didn't shoot. Or, a cop might just tell someone to do a bunch of different things to see if his hands go next to his waist. If they do, then "he was reaching for his waistband" and shooting him is legal.
