"The shit rises to the top"
As a child, there was a CID guy living up the hill from us, and one next door. The one up the hill had a caravan, and I have fond memories of him pushing it out of the drive, and it rolling away down the hill. The main memory of this event was him running down the hill behind it shouting "Stop!" I so wanted him to shout "in the name of the law" as well, but hey, can't have it all. He was promoted off the beat because he was useless.
The one next door.. A D.S. We used to call him Basher Barry, cos He was thick and very heavy handed, slammed everything. He was given a mini cooper as a "work car". Pulled up to the pumps, slammed the filler nozzle into the tank, pushed it through the pipe into the back of the boot. Where the radio gear was stashed. He filled the boot, and it was pissing out onto the ground. He put ten gallons in it! One of the mechanics saw him doing it, and stopped him before he got in and touched the ignition, as the radio gear coming on would have have set it off like a bomb. They promoted him to DI the week after, but they did give him a desk to drive.
