211 Crew
211 Crew is a large white supremacist prison gang based in Colorado. They are also known as Aryan Empire, Aryan Alliance or Brotherhood of Aryan Alliance. Authorities believe the name originated in the California penal code for robbery, but members claim 211 is a numeric code for BAA, which stands for Brotherhood of Aryan Alliance. The group's patch is a complex triangular symbol of interlocking arms, with hands grasping lightning bolts and the number 211 in the center.
