When I got the police involved with an attempted rape at the place I was being a security guard for, suddenly away went my benefits and hours. Guard working the camera and radios seemed to be working to help the guy get away. Not only directing folks away from the flight path but making sure the cameras only caught the back of the guy. I've long thought wild incompetence, but do now sometimes wonder if he was just more of a company man minimizing possible publicity exposure.
Also, just watched Freakanomics last night [half of it anyways]. Reason the solve rates for crimes is so high in Japan is because they don't record any crimes they don't think they can solve.
