The way you initially stated "their policy" implies an authoritative, 'it shall be done' position. If that were the case, it would be a written policy and you know that. I suppose it's possible I'm the only one that took it so literal as well.
You may question it and that's fine but you need to accept that other people have knowledge of the TDCJ system too, no matter how they acquired it.
Hot Damn! Here we go!
