The prison officers have to assess whether a prisoner will cause them problems. A chap can come in with the full intension of behaving but then become really really bad. They can kick off, fall out with other inmates, cause jeolousy in others or spread trouble throughout the whole jail population. That’s why cleanliness and lots of big intimate inspections are so important and it doesn’t matter how many times a guy is stripped and closely prodded and investigated. This guy is clean, but it’s great to watch him being revealed and have to open up his arsehole cheeks.
