You may have heard this story. I hadn't. Or at least not beyond the punch line, the cruelty part.
There was a man, a black man. He was angry a lot and one night when a friend couldn't afford $3 cover charge to get into a dance hall, he pulled out a gun and shot 3 people, I presume also black, but maybe not. One died. All over a $3 cover charge. He then drove away and stayed with different people for 3 days until his sister got him to agree to surrender to an old acquaintance, a cop. The cop was sitting in his mother's kitchen, said hi to him, and then turned back to speak to the mother, at which point the man fired 2 deadly shots into his neck and head.
He then walked outside, and fired a shot into his own head, leaving him partially lobotomized.
