we met christopher carrillo inside a heavily graded cell at san quentin. >> you give respect, you get respect. a lot of people say these guys don't treat us right. at times they don't, but it's hard when you've got a lot of people in here. can't be happy too much in prison. it's not disneyland. >> but another inmate at another california prison had a harsher view the cos. >> i hate cops. they're diabolical. they're petty. they present to the public that they're law and order, this and that but in here they'll stab you in the back. they write false write-ups. they got a hidden agenda. they want to keep us locked up in here so they make money. you know, this is a prison industrial complex. it's all about money. >> there is one place, however, where trust is put to the ultimate test. it's the prison kitchen. >> everything back here could be made into a potential weapon. those sheet pans are very thin and they're sharp on the edges. it only takes one of these guys to pick one of those up and they could almost cut my head off.
