The A.B., (also known as the Aryan Brotherhood or The Brand) is a prison gang numbering about 15,000 members in and out of prison. In March 2006, four leaders of the Aryan Brotherhood were indicted for numerous crimes, including murder, conspiracy, drug trafficking, and racketeering. According to the FBI, although the gang makes up less than 1% of the gang population, it is responsible for up to 26% of murders in the federal prison system.
The A.B. killed another inmate today.
