Cas is in the feds, but someone LIKE Cas will violate someone like Troy on the inside, because he knows how to move. Knows how to get the bangers and hide them, knows who to ask for permission to hit someone, or doesn't even have to, he's calling the shots, and once you are labeled, it's just non stop. You don't come out of your cell, or you have to roll up every line you hit. All Cas or Tax have to do is send a kite, and wherever he lands that's getting handled for you.
I was short time and teenaged when I was in, but I saw people get done dirty. Saw a dude get stomped out in the showers and had to RUN with his stuff bleeding to the door and yell for the deputies. They told him, "tell them you cut yourself shaving", because he was covered in blood.
