Texas refuses to give access to policies

I really do appreciate your help. But I have another favor to ask you. For a long time I have been trying to get a copy of the TDCJ Policy so that I can better understand how to fight every case that be written up against me. Cause these peoples will write peoples up for no reason at all. You can’t imagine how corrupted this system is. They don’t let us get access to the most important policies that we need to be able to fight for our rights. I am a 12 hour worker in here in this prison a day. And sometimes my supervisor don’t feed me telling me they don’t have to feed me a hot meal. Just a Johnny Sandwich. Which isn’t right at all. So if you can please provide me this policy concerning TDCJ, I will appreciate it very much.
