I believe police officers do a very difficult job and there isn't sufficient funding for the growth in population, which is very noticeable in London however it seems they do waste valuable time on really trivial incidents.
It must be very frustrating for good officers that they are asked to investigate "hurty words" and also when they see prisoners who they believe are dangerous not on remand due to lack of prison places.
Do we need to see hours spent on trivial crimes? The Arday case had an investigation open for 4 months?? I'm sure it's because the officer was afraid of the backlash if he closed it.
Police do reflect the public but it's their bosses who should be accountable. Who review cases? Is there enough experience or resource?
