Not trying to defend the police to any great extent, but I wonder if forum members have any concept of the number of calls a mid-sized county force, say 3600 officers and around 1500 police 'staff' deals with every day. It's easily in excess of 1500, peaking nearer 1800 in the summer silly season which we are in the middle of. They still prioritise on the protection of life and property in that order, so on Friday night not that far from Derby centre they would be unlikely to have anyone for property recovery until around 0600, maybe 0700 when the day shift come in - and that's assuming they aren't picking up the leftovers of the night before.
