It looks like Lovelle Mixon killed four Oakland cops because he didn’t want to want go back to prison on a minor parole violation. According to the Chron, the 26-year-old ex-felon was facing a mandatory six months for failing to show up to a meeting with his parole officer. Which begs the obvious question, is supervised parole even a good idea? When a convict finishes doing his time behind bars, why isn’t he just released back into society? Is there any proof that supervised parole actually helps ex-cons adjust to life outside of prison? Or is it simply a system of strict rules that sets ex-cons up for failure? Or worse, is it a system that propels former prisoners to act rashly and do anything to avoid being put back behind bars?
