The way the american gangster William "Action" Jackson was murdered wasn't very nice either.
Quote from his Wikipedia article: "Jackson was impaled through his rectum with a meat hook, hanging a foot in the air, while being questioned by mob enforcers. Jackson kept insisting he was not an informer but his torturers did not believe him. They stripped him naked, smashed his kneecaps with a bat, one of them shot him with a gun, broke his ribs, stuck him with sharp objects, used a cattle prod on his penis and anus making him lose his bowels, burned parts of his body with a blow torch, and told him how they were going to kill his wife and children if he did not confess. Then they left him for three days until he finally succumbed to his wounds."
