“Hands up! Just shoot!”
Well, the other guy had his hands up and they killed him. Why should they worry whether or not these 4 have their hands up.
They got away scot free, with Ruby Ridge and Waco. Assassinating these 4 guys, if they do indeed do that, will be child's play. Easy to get away with it.
They could film them on their knees, being shot in the back of the head, and the executioners would be hailed as heroes. Welcome to the Soviet Union.
