It's a bit weird because I want to go in your direction but something is wrong here. Ask yourself this question, why is it going happen again? For me the answer clearly points to something else than the police, it points to society at large, the judicial and political systems have the same prejudice against african americans and I assume hispanics/latinos, the education system and the average american often has that prejudice too. None of these institutions are monoliths but on the topic of race american society is poisoned to the point where wherever you look a significant minority will create havoc at some point. And I don't see how they are going to fix that.
This situation reminds me this quote, a finger pointing at the moon isn't the moon.
