“Blood in, Blood out”. This is the very motto of a very well-known prison gang for racism in the United States. Although there were numerous conflicts that aroused in both state and federal prisons in the United States, the Aryan Brotherhood was at the top of the list for violet behavior in acts of racism. It started as different white gangs in the San Quentin State Prison merging together to form the Aryan Brotherhood in 1960. It is only primarily just present in the federal and California prison systems. The original way to gain a membership to the Aryan Brotherhood was to be Irish youth as a subculture, the united nations agency at the very beginning classified them as the “diamond tooth gang.”  However, many other prison gangs now also use the “Aryan Brotherhood” as part of their name, such as the Aryan Brotherhood of Texas. They are independent and unrelated to the “original” Aryan Brotherhood. Even before new potential recruits make the connection with the Aryan Brotherhood, they need a way to “make their bones”. This is done by usually murdering or some sort of assaultive behavior towards a corrections officer, or to a rival member of another gang. This is the whole “blood in” part in the Gangs motto. A major rival of the Aryan Brotherhood also behind bars is known as the “Black Guerilla Family” Certain methods against the BGF are the reason the Aryan Brotherhood is classified as the primary white supremacist gang in the country.
Today, the gang operates both within the prison doors and outside the prison doors as a very big major criminal enterprise. As a crime organization, the Brotherhood participates in; drug trafficking, male prostitution rings, gambling, and extortion inside the prison walls. On the streets however, the gang is involved in practically every and any kind of criminal act including; murder-for-hire, gun running, armed robbery, methamphetamine manufacturing and heroin sales, counterfeiting and identity theft. Creating large amounts of money and the racist members opt for money shows that gang works with not only the Latino Mob but other gangs as well for profit.
