My view may be colored by living in occupied DC, where there are a lot of armored vehicles and heavily armed federal security forces, some of whom appear to be quite comfortable amping up the violence levels. Given their past actions, black people with guns would be a time-honored excuse to say they felt threatened.

I have a number of coworkers who are veterans and while they’re generally confident that the military would refuse to follow general orders to attack civilians, nobody wants to test what might happen in confusion if they’re deployed to backup the police. All you need is one mistake and a lot of people can get hurt before the confusion clears.
