. >> surveillance footage from the visiting room at kern valley state valley prison showed how such bizarrechniques work. >> this is actual footage from our visiting area here. we have a suspect attempting to introduce narcotics into the institution. that is the suspect sitting right there. as you can see, he's looking around. there's another inmate, the inmate directly in front of him is attempting to block the cameras. as you can see, he's halfway off the chair, that's what kind of piqued the curiosity of my officers, the way the individual is sitting. that's usually an indicator that he's going to possibly attempt to introduce narcotics. you can see his right hand, there is an orange object, within a matter of seconds, that will be secreted in his rectum. you can see there he goes. at that point, he's pretty much introduced narcotics into the institution. unfortunately for him, we had staff in the area monitoring the video cameras and we watched it as it unfolded and we were able to apprehend him and his visitor. >> for this attempt to smuggle one ounce of marijuana into prison, the inma

a fact dramatically illustrated during our visit to kern valley state prison in california. >> it's all we got, work, work, work, you know. >> when we met james randall, he was working his prison job helping officers serve food to his fellow inmates. when we sat down to talk in his cell, randall seemed to only have one concern. how his shaved head looked on camera. >> there's no lint on my head or nothing? >> no, you're fine. >> i'm cool. i got a gang out of it. i don't want to be shining. i'll be shining like money. >> when you interview people in prison, you know they are in there for a good reason. and when you meet them, sometimes they're very likable. they might even be somebody you think you could be friends with. but sometimes you end up hearing a jaw-dropping story. the day we met james randall, we heard a jaw-dropping story. >> originally i came to jail february 21st, 1981, convicted in san bernardino county for murder/robbery. >> given a sentence of 34 years to life, randall was 18 at the time of his conviction. but his rap sheet started much earlier. >> i have been gang bangi

dennis hamilton, in the hole, solitary confinement at in the administrative segregation unit at kern valleyn. it was the second time his refusal to share a cell had landed him there. but his time in the hole was about to end. and he was scheduled to return to general population, where sharing a cell is mandatory. >> to me the cells are too small. i think the cell in its breeds an environment for homosexuality. >> dennis hamilton was an unusual inmate. he just believed he didn't have to live with another man. i think he had a fear about living with another man. >> and to me it's like you don't even want these people in society, but you want me to feel safe inside a cell with this person. >> ironically other inmates might not feel safe around hamilton either. he's serving a life sentence for kidnapping, carjacking, robbery, and assault with a deadly weapon. nine years in, he's only now decided to make his stand against taking a cell mate. >> there's no rule that says i have to take a cellie. two, i don't want to live with another man for the rest of my life. >> 127. >> the prison officials di

. >> we met officer epperson at the kern valley state prison in california.nly with pepper spray and a baton, he's the lone officer responsible for supervising the inmate kitchen staff. >> i have six, seven inmates back here now. i've got one sitting on the line. granted, i got four, five cops outside that door. that door's locked. there's only one dude out there with the key. you have to trust them to a certain extent. they have no reason to assault me. unless they're totally pissed off or i disrespect them. >> among the inmates epperson places his trust in is the number two cook, carter hill. >> tell me what your sentence is. >> murder. >> you're here for murder? what's your sentence? >> 51 to life. >> you know, it's interesting. sometimes there's this dynamic in prison when you're interviewing somebody, if there's a corrections officer and an inmate together, they'll pretty much watch their ps and qs. they'll tell you into the camera what the other guy wants to hear. but when we met carter hill, we got some real brutal honesty that day in the kitchen. >> i

valley. it happened in an alfalfa field near the kern county town of weed patch. mark sayre asked, simply what happened? >> reporter: this 34" pipe which ripped over near bakersfield is just slightly larger than the pipe that ruptured in san bruno except this time the rupture was caused when pg&e crews were carrying out testing by forcing high pressure water through the line. it opened a crater in a field. nobody was hurt. pg&e says that the failure occurred when the 1950s era line was being pushed well past its maximum allowable operating pressure. >> the failure yesterday came on the longitudinal seam weld which is similar to the pipeline involved in the san bruno accident. >> reporter: since the san bruno blast in september of last year, pg&e says it has pressure tested about 120 miles of natural gas pipeline and will test a total of 150 miles before the end of the year. after scrutiny by regulators, the utility is testing lines where it lacks records of previous strength tests. >> this is exactly why we're doing these tests. if there are weaknesses within our
