I read the book "the westies and jimmy Coonan was as bad or worse than Featherstone, Coonan was a real maniac, who killed a mobster named mickey spillane to get the top spot in the westies, I compare Coonan to Anthony casso, he was that blood thirsty.
jimmy coonan was a bad dude but he wasnt as crazy as featherstone since mickey actually had mental issues. The spillane killing was personal for jimmy since spillane had beat up his father years before
