There does seem to be an ironic justice - in an entirely negative way - in the sequence of events.

Random black men, either innocent of any crime or maybe guilty of very minor legal infractions, or "driving while black," shot by white police officers.

A few days later, random white police officers, similarly innocent, shot by a pissed off black man.

It's not right, but how much longer can it go on, where apparently innocent blacks get shot before it seems like a logical consequence that random innocent white cops are shot? And don't get me wrong; I think I've established my opinion well that I've no quarrel with perps of any race being shot while committing crimes.
