Not long ago, at a certain ranch out in Nevada, a bunch of white folks were waving around real guns that they'd brought with them for the expressed purpose of shooting law enforcement officers. Most of them did not even know the rancher who owned the place, and some had come from many miles away armed for a confrontation with federal agents.
That's what's mind-blowing. Here in America, you can carry around a semi-automatic rifle modeled after a military weapon, publicly declare that you'd like to use it to gun down a cop or federal agent, and it isn't a big deal so long as you're not so black.
Wave around a toy gun (modeled to kinda look like a real gun) in a store while being black? Shot on sight.
