If you work in the nick you accept that some prisoners become accustomed to total humiliation. To some extent they expect it and its no-ones job to be concerned about why a man wants to be strip searched. If a man acts in a way that you suspect that hes stashed contraband up his arehole then you have no choice but to inspect him thoroughly. Its just a straight coincidence isnt it that the places men choose to hide stuff are also their sexual private parts!
