Here is a direct quote from Ralph Salerno, widely considered the Justice Department's No. 1 expert on organized crime, on Giancana's supposed "invovlement" in the Kennedy hits:

The FBI had very extensive coverage on the leaders of organized crime in Chicago, with Sam Giancana and others. They tape recorded him in the Armory Lounge, which he sort of made his own personal headquarters. Sam Giancana doesn't show any foreknowledge at all. After the fact, in a discussion, he's talking with one of his accomplices about Oswald, and they said "What kind of guy was he?" And Sam says "I don't know what kind of guy he was, but he was a pretty good marksman." Now that doesn't sound like the comment of a man who had retained the man he was surprised to find was such a good marksman.

Q. In what upstate New York town did Meyer Lansky control gambling?
