California Reeling - California, in Financial Crisis, Opens Prison Door (RANDAL C. ARCHIBOLD. New York Times. March 23, 2010): "California is the only state that places all prisoners on parole at release, no matter the offense, Professor Petersilia [formerly of UCI] said, and usually for one to three years. If a parolee is arrested or fails a drug test or misses an appointment with a parole officer, the offender lands back in prison.
Now, low-level offenders will not need to meet regularly with a parole officer and must be convicted of a new crime to be sent back..."
