Yea I agree it seems like he got a crush on accardo and the hump. That is because they didn't act like dicks when they were approached by him. Unlike Giancana and Spilotro.
It's all about how you carry.yourself. The first two I mentioned died in bed the last two never made it to bed.
roemer and his fbi cohorts, planted some bugs in some Chicago joints, but, they never made any arrests that I know of.
I read all of roemers books, he crows a lot about how much he and the fbi hurt the mob, but, at the time he was active, I don't think he hurt them much at all.
