Tesco,Stable Door

From what the local Tesco supermarket staff I pick-up tell me it seems that Tesco are shutting the stable door after the horse has bolted. After embarrassing security CCTV found it's way onto the Internet a few weeks back security has been drastically increased. But staff are unhappy about being subjected to compulsory searches as they leave the store. This is leading to staff being delayed, leaving work by up to thirty minutes and outrage by some female staff having to be searched by male security staff. This my source tells me is due to a female security staff shortage. If staff request being searched by a member of the same sex they are told they will have to wait, leading to even more delays in leaving for home. Obviously the security problem was caused by the security staff themselves, so who watches the watchers?
