Hahhahahahaha...totally. Actually he took an IQ test in prison and he was borderline mentally disabled. True story. I think he scored less than 90, which at the time classified him as an "imbecile."
His great skill seems to have been killing people indiscriminately.
Anyway, a lot of these odd Chicago posters who worship the Outfit absolutely worship Sam Giancana. It is kind of funny, really. They sit around talking about him like he's Paul Bunyun!
