Well, if we're just going to nitpick the "realism" of the show, I really had a hard time believing that a relatively small Jersey family could get the okay to kill a New York boss (Phil Leotardo). But we all hated Phil, so we looked the other way. And from that point of view, that's why I think Tony dies at the ice cream shop, in retaliation for Phil getting whacked. But that's a subject that's been done to death here, so I'll leave it alone.
