guy and i don't believe in violence. that's a damn lie. it was my responsibility on the yard to ensure that, one, our people were not harmed by another race. i took care of the drug debts if one of our people became delinquent in a drug debt to another race, it was my responsibility to either cover their drug debor have them stabbed, in which case we would send one of ours to stab them. >> duncan's loyalty to his gang was also inked into his skin. >> my stomach, i have a war bird. these lightning bolts mean something, and if they were solid that meant that there was a kill, that you actually killed the victim. being shaded in like that, that means i did put in a racial stabbing, but it wasn't a kill, and it wasn't from lack of trying to my part. >> duncan's tattoos weren't only about gang life. some were about his love life. >> couple of wives' names up here. charlene, that was a prison employee.
