The 'black on black' expression is in response to claims of 'white on black' crime which is what started this whole thing. Crump implied that whites were gunning down black kids and it needed to stop - which it would, if it were true The reality is that interracial violence is rarer than intraracial violence. That a minority makes up the majority of crime statistics is what concerns people.
"Parents need to have a conversation to tell them not to run from or disrespect the cops" ... what the heck? Why don't kids know this anyway? Why don't they know to treat EVERYONE with respect?! Isn't this the heart of the problem?
