Al Capone personally kill 2 men with a baseball bat.
I remember that! Vicious. Now a guy like that, his Capos have to think 5 times before double crossing, and even if they come to a consensus to get rid of him, how do you get him? That's not easy. You can't get him at a meeting he called. So you must do some sort of public ambush, but if you do a street ambush, a night club raid, or a drive by, Capone was ready by being surrounded by body guards and a tank masquerading as a limousine. He just wasn't havin it.
