What was different
White men can wander around in Targets and Chipotles and Starbucks with actual rifles and, as far as I can tell, nobody calls the police about them.
John Crawford, on the other hand, picks up an unloaded BB gun off a shelf in a Walmart - in, by the way, an Open Carry state - and customers call the cops who shoot him dead. Which was "proper procedure".
So what was different that time? Simple, predictable, and tragic.
John Crawford was a black man.
