My Lords, police attendance on a crime-by-crime basis is a difficult thing to sustain. The police should attend all reports of crime if the victim wants them to or if it is a very serious event, which is something I have always pursued, but should the Government not also work with the College of Policing to share the best evidence about what highlights those most at risk? For example, Professor Larry Sherman, recently at Cambridge, highlighted a high correlation between suspects who had threatened suicide and people who eventually became murderers of victims they had previously threatened. We had previously been told that threatening the victim prior to their murder was also an indicator. Both matter, but the police’s response needs to be based on good evidence. I am not convinced that the college has yet got that connection between the evidence base and passing that on to the police to share, so that their training improves.
