If you work in a prison you have to accept the notion that some prisoners become accustomed to ritual humiliation during strip searchs. To an extent they come to want and enjoy it. It’s not your job to be concerned when a man is strip searched, you still have to do it. If a man acts in a way that you suspect that he has contraband up his arsehole then you have no choice but to inspect him intimately. It’s just a straight coincidence isn’t it that the places men choose to hide stuff are also their sexual, stinkiest parts?
