I once saw someone die by jumping into a canal. The police reaction to this event was the opposite of fiction. In novels, the police rush to the scene, a battery of high-tech forensics is used, a pathologist is called and examines the body in situ, and all hands are on deck in professional, efficient manner. In my real-life example, they did not care. Less dramatic cases are treated with similar lack of interest - for example I was once knocked off my bike by a motorist turning right across me. He initially stopped to see how I was, then drove off. A witness wrote down his numberplate. I reported the incident to the police, but by the time I got home from the station about an hour later, there was a message on my answering machine saying that they could not trace the number so were closing the case. Some years later, I had a much more serious accident caused by a hit and run driver. The police were notorious by their absence. [I have had many positive experiences with the police over the years, but not so far as observing them trying to solve actual crimes.]
This is not good.
