My hierarchy structure comes from my friendship with many Prison Guards over the years, many became street cops along the way. When we would get together after a long day protecting and serving, the former guards would regale us with story after story of the shenanigans they encountered during their prison service time.
Made for a great time while we enjoyed our favorite adult beverages. LOL
Yep, I saw some rank stuff, that would make you shake your head, when I was there too, especially in the nut ward.
