CC, I believe so, too. A few people here have said that the Outfit wanted to kill Roselli years beforehand, but Giancana was protecting him. As soon as Giancana went, so did Roselli.
Hoodlum, I agree. Saw Becker in one of the Bill Kurtis documentaries from the '90s on youtube a few months ago. He sticks to what he knows and speaks clearly. Interesting person. There isn't much info on him out there. He worked for Gus Greenbaum when Greenbaum was whacked, so I'm sure he laid low for a long time.
