Spent 7 years in federal prison, 5 in Marion and 2 in Leavenworth. In reality it breaks down to group size. Marion did not have a large LCN population, so the mob guys I met were pretty low key, didnt look for trouble and were pretty much left alone. At leavenworth there was a larger LCN population with several lifers, they were much more involved in prison politics. I do know that protection is paid, when I first went it, it was cigerettes, then they made it smoke free and it then became stamps and commisary primarily. I know there were at least two guys in leavenworth that I knew who gave some AB guys 150.00 in commisary a month for protection. No one messed with the LCN guys as far as I saw.
