Over the past 6 months there has been an escalation of violence, firearms, and vigilantism.
In a high tension environment (I think we can all agree that the protests are tension filled) it only takes a one individual to lose their cool. This could just as easily been Charlottesville, Louisville (for god's sake there was an accidental discharge there), Portland or any number of other cities.
This is a tragedy but none of us should be surprised.
