the time of our visit, wilson had just completed an anger management program that deputy warden tony patterson arranged for him to take in his cell. >> he needs to grow up. immaturity. you know. but he's working on it. >> i got kids, man. everybody going to change one day. >> for wilson, change is essential. most of his sentence for assaulting the officer will overlap with his original sentence. but just a day after we interviewed him, wilson's anger surfaced again. when he saw our crew on the exercise yard, he greeted them with an obscene gesture. >> one [ bleep ], y'all, two, retire. we don't need y'all around here no more. your time up. >> some days they like us. some days they don't want to see us. i think that's kind of a function of being in prison. you're mostly pissed off all the time anyway. if you can take it out on the film crew, why not. >> though wilson may enjoy his freedom again, it's too late for one other inmate whose anger has had disastrous consequences. >> my name is jesus garcia, i have been incarcerated for nearly 12 1/2 years. i'm incarcerated for first degree murder and
