"Tolerated terrorism", hmmm. I guess back then no one said a word of that and other acts of terror leading to the murder of innocent black men, women and children occurred. Like the three monkeys who see no evil, hear no evil and speak no evil. In the 30's, there were radio programs that had depictions of racial intolerance. Humphrey Bogart was in a exploitation film called The Black Legion. It was about a man who joins a hate group similar to the Ku Klux Klan but soon learns the hard way about it. I even recall the black church burnings of the 90's. The arsonist left a recorded message on an answering machine using a scary voice talking about the fires of aryan hell being visited upon the churches. Terrorism plain and simple. Right now if klansmen burn a cross on your property it's an act of terrorism.
They don't call that bama city Bombingham for nothing. The use of explosives to intimidate Blacks in that city was almost endemic.
Dig up the body, smother it with tar and bash the bones, piss on it and then throw it back in the ground, covered in cement and Sulphur. And that is being nice.
