That's why prison is never rehab for hackers. They just network with the street criminals and come out super criminals with full cred like Max Vision or the software developer kid here where I live that did a bid for bank fraud, met some gangsters in prison, paroled as a ranking member in their violent dial a dope crew and police have been unable to break up the gang since he joined and took over the comsec and allegedly money laundering for them. They accused him of being able to leak the whereabouts of rivals to his own gang too by social engineering the media and police, plus hacking their blackberries. Strong security knowledge + violent criminal pact with bikers = not good
