I find it funny how some people expect police officers to be some ninja who can safely disarm someone with a knife with their bear hands.
I've never seen any of the people criticizing this explain how this was supposed to be resolved non-violently. "Hey can you please not stab that person?" Don't think that was going to work.
LeBron is apparently not tired of seeing black people killed by other black people which happens far more often than their getting killed by police and might have happened here had the cop not intervened.
If "activists" cared even half as much when a black person gets killed by a black as they do when its by a white I might take them a bit more seriously but as it stands these things are just excuses to bash whitey. Even if in some instances it is justified like with Chauvin.
