One of my colleagues did a case where this guy was the expert witness. When I was a pupil, my pupilmistress prosecuted a trial where the Officer in the Case was a DC Wombel who was attached (inevitably) to Wimbledon police station.
We got on like a house on fire, but I didn't learn a great deal from her apart from which wines she and all her friends preferred, along with the names of the managers and the phone numbers of the local bars and taxi firms. This was because I spent at least one day a week trying to track down her coat/bag/robes/papers on account of her habit of misplacing them when she was "in her cups". My co-pupil very much drew the short straw and ended up with an absolute harpie, now a top Treasury Counsel silk, who worked her half to death, including once receiving a phone call from her at 230am demanding she draft an application to exclude evidence ready for resumption of the next day's trial at 10am. We were probably one of the last cohorts to do a proper hardcore old fashioned pupillage - sadly, they're much more structured and more or less compliant with employment and equality law nowadays!
I've parked my car at that very spot as it is now part of the grounds of Hertfordshire Sports Village where they have indoor cricket nets that one of the teams I play for use for winter practise.
