Gov. Pat Quinn suspended Illinois' program in December after the AP found that hundreds of inmates were being released too early. About 200 of the paroled inmates were returned to prison within the first four months of the program because of violations.
Precisely what happened is very hard to figure out. The law was mainly about state prisons and parole, but the stories of early release all focus on jails. It may be that these are parole violators, released from jail where they were being held on parole holds for non-violent parole violations but who are listed as violent offenders because their original commitment offense was violent. In any event, I have some research assistants working on this and will report back. In the meantime, the fact that California has a lame duck Governor will protect the current program for at least the ten months or so until the election. But if this kind of toxic reporting continues, look for the Gov-Elect to announce plans to cancel it before their even inaugurated.
