Sylvia - I get your passion. Black and Brown men are probably very scary to you. But "unarmed" means there really should be no reason to use lethal force. Cops are trained to use a plethora of techniques that are non-lethal - it's just clear that more and more cops are surpassing their training and jumping to lethal force more quickly and, in many cases, unnecessarily - especially against black men and boys. 

"Protecting" a community by labeling it "criminal" and brutalizing it is similar to the logic used by every dictatorship in history - speaking of ignorance. And not sure what evidence you have or logic you're using for your "...letting out white predators earlier so they can go back to predatorializing on white communities..." rant.
