There are accounts of classic murders here - Christie, Heath and Haigh were all brought to justice on Scott's watch, but perhaps more important is the reminder of just how damaged British society was in the immediate aftermath of the war. Crime boomed as never before and there was a desperate shortage of police officers to try and contain it. It was not until Scott that such radical innovations as women police constables and police dogs became standard. Even so, Scott makes it clear that policing in those days was about crime reduction rather than counting arrests. It was also on his watch that traffic cops came into their own but, amazing as it seems to us now, advice and warnings were prioritised over collecting convictions. There was more crime and more civil liberty - if only such a concept troubled our modern legislators.
