This was just posted on /pol/, and in the thread there are several people who defend the actions of the police. Why? Because he was sitting down when he raised his hands, instead of standing up like they demanded.
Imagine if any private security firm did this; would anybody continue to support them? I wager the answer is no. But for the case of state services, the answer is yes. People are so accustomed to low-quality returns that even when a state works against it's advertised goal (to make society safer in this case), they can come up with a justification for why it is okay. The police in this video could have just came into his house, shot him, left, and the reaction would be the same.
