This is not a stupid statement. He is one of the few black leaders who points out that cops are people, he acknowledges that they bring baggage to work everyday, just like everyone else, except they have to make a snap decision whether to shoot or not, and this SNAP decision is certainly affected by bias and experience, which is how the brain works. Bias exists precisely to make a snap decision. Hundreds of unarmed people of all colors are killed by police every year, the reason the protests were so multicultural supports this fact. Cops are overburdened to deal with a crush of mental health issues, social problems, and the occasionally extremely violent traumatized individual who happens to be heavily armed. This reminds of the soldier quandary. Soldiers would be much better off if we used diplomacy, and created situations where soldiers were needed less often...cops would benefit from being demilitarized, and investing heavily in every arena that can deescalate a situation, with an elite trained force able to respond to true violent situations, forces so well trained that they aren't susceptible to shooting a guy with a fake or an invisible knife a half dozen times.
