What you don't know is that mark got 51 months in 1999 for felon is possession of a firearm. He should have gotten the Armed Career Criminal charge. He was also arrested with 50 grams of heroin on him that he was never charged with. It is already known to his codefendants lawyers and it will be public shortly. He got out in 2003 and got violated for dirty urines twice, so yes he wrapped up his sentence in 06. Federal probation does not care if you are a rat.
