A couple of points:  As a middle class white father, years ago I told my son who was in his early teens that all he knew of any police officer is that he is armed and dangerous and the only sane course of action is total compliance.  To do otherwise is to invite death.  Yes sir, No sir, whatever you want sir!  To pull a weapon of any description is nothing less than "suicide by cop."

When I see anyone, black, white or purple, regardless of race, dressed as a banger (hoody, baggie pants, etc) and approaching me, I avoid contact if I can. It isn't just if they look like Obama or his son.

Every human life matters!  Regardless. To say otherwise is total hypocracy.  Taking lives is not a solution.
