Based on dirty figures you have a ratio of 1 officer to every 399.6 people in England and Wales.
Taken from 2023 police figures of 149,164 officers v 2021 Census - 59.6million people in E&W.
Now consider that many police work shifts. Usually the 6 on 4 off monstrosity when in a uniform role. For the purposes of this calculation, we'll assume everyone works that pattern including detectives, management etc and ignore all the training days / court days /annual leave / maternity / sickness and any other abstractions that keep people off the front line day to day!
That requires a rota of 5 teams on rolling shifts of 2 days, 2 lates, 2 nights, 4 off.
That means a MAX of 29,832 on duty at any time across E&W.
The ratio now drops to 1 officer to every 1998 people.
The reality is much worse.
I've worked weekend and bank holiday nights in a city of 200,000 people as the sole detective constable available for the city and the surrounding 50mile radius.
Meanwhile, colleagues on response have had just 12 of them for the same area. No neighbourhood teams, traffic off being just as busy elsewhere in the county, one dog for the whole county, and no magical boxes of uniformed officers to bring out in the event of major trouble. There's a magical box of detectives for Major Crime like murder (worked that too).
Right now, every specialist department will be back filling for all the riot trained teams now being sent all over the country. And at some point they all need sleep, food, drink and the ability to pee!
That means fewer and fewer people to attend domestic abuse calls, rapes, burglaries, pub fights, thefts, RTCs - the daily calls.
Civilian support staff are also working overtime, especially control rooms, investigation and intelligence teams.
