So how do I know I'm protected if I decided to join the AB in Prison?

Is it guaranteed that someone will have your back if say a black was to jump you and try to kill you?

Can't a guy just be cool with everyone and respect others while keeping to themselves? Are people really going to harass you in prison if you don't want to be bothered and don't have any intention disrespecting anyone? Are guys in prison really gonna waste their time with a guy who say was in there for a crime that wasn't something that would piss them off such as a racial killing or something like that?

Say I go in prison and all I want to do is sit in my cell and read books and workout in the yard. I never say a word to anyone. Are people really gonna come after me?
