Part of what we do--I'm a warden of a medium-security facility--is that as we gather information.... All criminal organizations have a risk inherent in our facilities. We assess risk. When some of the offenders are assessed as maximum security, they will be transferred to a penitentiary suited to managing their risk. That is the reason for some of the transfers.
Some of the other transfers we do are for programming purposes. A lot of the time people will try to drop their colours, or disaffiliate from a gang. We will try to do that locally, but a lot of times we will transfer an offender to another institution to give him a start so that he can break away safely from his gang.
Those are a couple of the ways gang members can spread throughout the penitentiary system.
