The prisons are not opening their doors today. The 6500 prisoners to be released early will be released over time. You are correct that 85% is NOT being reduced to 50% as vilevt crimes, serious felonies and sex crimes are excepted. The new law gives extra credits for completing the GED and certain other programs as well as those extended to persons working in fire camps. You can find the new law at SBx3 18; Stats. 2009, 3 EX Ch 28. A law librarian can help you find it as it is not reflected in some of the new code books for 2010.
