Daryl Johnson, leader of the Domestic Terrorist Analysis Team whose job it is to monitor the activity of right-wing militias and domestic terrorist groups, said that white supremacist organizations in prisons are a "...radicalization threat," committing acts of violence inside prison, and then in the larger communities after release. Johnson named the Aryan Brotherhood, Aryan Brotherhood of Texas, and the Aryan Circle as examples of white supremacist prison-based gangs which are radicalization threats.[24]:325
