I know only what I have read and it seemed like a set-up. Birns would not need to borrow money from anyone to loan that much to Greene. Birns knew Greene wouldnt pay money he never got back. I do not believe for a second an expirenced loan shark would be as sloppy and careless with a loan from the Gambinos as Birns was in this instance. Tho Greene was not yet huge competition to Scalish and the Cleveland fam at this time they were aware by this time Him and Nardi were doing thier own thing and I dont think they were ok with it. It gave them a legit reason to go after Greene and prematurely stop his rise in my opinion.
