Just Wondering

We have all these people, including our idiot in chief Obama, condemning the police in the shooting in St. Louis County, MO.
Have any of these useful idiots complained about the Black on Black crime in their city/neighborhood?
Racist Obama hasn't.
Have any of these rioting thugs protested a Black kid being murdered by a Black suspect?  Racist Al Sharpton hasn't.
So, when will these Black protestors start protesting Black on Black crime?
Just wondering.
