I know that after 2 years of sentencing in fed court you can't start cooperating. Famous turncoat burt kaplan case example. He's 7 yrs into his 15 for weed. The feds needed him so bad when Burt told them he paid to have another inmate assumed the feds indicted him and used that crime as a way to get him the 5k letter for resentencing. Don't know how the state does it but the philly state let 2 federal rats rot in there state system after the fedset them go only for the pa. Doc to hold them on the state charges roger vella did like 10+ years and harry hunchback guy how shot sal tests the turned fed rat. They still need a 2 guy to help nicodemo story's.
