There is a strict procedure which must be followed when a new inmate is strip searched. Any deviation from that will land the prisoner in hot water - leading to verbal humiliation which compounds upon the physical humiliation of having to strip naked before these cruel strangers. Really these officers are just acclimating this tough straight criminal to what he's going to have to face daily - he will have no privacy and be subject to these regimental strip searches whenever the pervy guards feel like inspecting his butthole. By the end he is looking suitably humbled.
