I'm not the first to suggest this but consider the aftermath of an incident in which a black man got out of his car in a white neighborhood, confronted a white teenager without a record and then shot and killed him. There was confusion about what happened between the time the black man got out of his car to approach the teenager and shot him, but it was known that whatever happened, the black man voluntarily confronted the kid and then the kid died.
Now imagine a black man ever getting off with all charges dismissed.
America. It's quite a country. In England you have to be a cop to kill a kid; we've subcontracted it to self-appointed neighborhood watch. Tennis shoes instead of mopeds, neighborhood watch instead of the police. America - where even injustice costs less.
