I guess our gang populations mirror many of the gang populations in the community. So if we have a lot of street gang members of various ethnic origins in the community, offenders are often already affiliated with a gang prior to their incarceration. So we will try to manage those groups.
Something else that is related to your question of why we would move individuals around is the option of segregation, which is an extreme option for us. When we have an inmate who's in segregation, we try to devise a plan to return him to the general prison population, so he can participate in rehabilitative functions such as programming and employment. That's another reason we will move offenders around to various penitentiaries.
