If you work in a prison you have to accept the notion that some prisoners become accustomed to ritual humiliation. To some extent they come to want and expect it. It’s not your job to be concerned about why a man wants to be strip searched, you still have to do it. If a man acts in a way that you suspect that he’s stashed contraband on and in his body 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 private parts!
