The US Department of Justice says the Aryan Knights are a white supremacist and white separatist prison gang with over 100 members, founded in the 1990s.
I would think 12 million is a more concerning number. Did you see the 100+ illegals overwhelming law enforcement at the border in a really dangerous situation recently? One arrest and the rest were given their swag bag for transit into the country. Or did you read about the snafu with paperwork and 200,000 illegals "losing" court dates for paperwork mysteriously lost or forgotten?
Just citizens bearing the brunt of it, and at times, being slaughtered or raped like sheep. Not amusing.
