Shamrock Tattoos

A tattoo of a shamrock is associated with the white supremecist prison gang known as the Aryan Brotherhood.

But many people of Irish descent who are not at all affiliated with the Aryan Brotherhood often have shamrock tattoos. These people who are jailed are forced to cover up their tattoos by the AB as they aren't allowed to wear the Aryan Brotherhood tattoo even though it is generaly perceived as an Irish symbol.

Inside each of the three leaves of the shamrock is often found the number 6. St Patrick used the shamrock to teach ancient Druids the Holy Trinity, and by adding a 6 in each leaf the Aryan Brotherhood makes a comment of turning good into evil. They are also known to hide the 666 or the letters "AB" in other, more mundane tattoos.

The Aryan Brotherhood is also known to use 12 as an identifier, with the 1 symbolizing the letter A and the 2 symbolizing the letter A, other White Supremicists gangs, the Aryan circle uses 13 as their symbol, with the same derivation.
