Police officers DO NOT POSSESS THE KNOWLEDGE to be able to triage such reports accurately. The required knowledge is almost never at hand. That is not only the case in the UK.

I am so sorry, Gracie, and Gracie’s family. Along with other (mental and physical) health-related issues, stalking and harassment remain the most difficult issues for the police to deal with because they’re unequipped to handle them and it’s rarely high on their agenda as so many reports are silly “he said, she said” quarrels, filed not in fear and concern but merely to spite another person. This field is much more a public health matter rather than a policing matter.
