during our shoot at san antonio's bexar county jail, we did meet some inmates willing to talk. they were in a special protective custody unit for gang members who had had enough. >> the ex-gang unit was night and day different than any of the active units we had been to. the inmates had a sense of relief that getting out of the gang provided them, and it showed. >> the ex-gang unit is the only place where those affiliated with warring gangs live together peacefully. but they're fully aware their decisions to leave their gangs carry consequences that could follow them forever. >> we always tell any ex-member of any major prison gang, your life is in danger. there is somebody out to get you. it is going to happen. just remember that you were part of a criminal enterprise and you left it, and there is by their bylaws a hit on you. >> that's the way it goes. you're in it for life or you're dead, you know, there's no -- there's no way out of it.
