Few years ago I had a job where I installed E-911 equipment and Computer Aided Dispatching systems. Was at a small town dispatch center with a co-worker when a policeman came in at the end of a shift and had this metal thing he took from some kids that were loitering around closed busineses. He didn't know what it was so my co-worker says "I know what it is, here I'll show you". He tool the tool and the policeman outside the dispatch room and locked and shut the door behind him, then we heard the door knob jiggle as he demonstrated that it was locked then in a few seconds popped the door open and let himself back in. The policeman that was with us then took the tool back and said he should arrest us just for knowing what that was <img src="/images/graemlins/smile.gif" alt="" />
