The police force recruits heavily from ex-forces. But not officer class. For all the fetishisation of the military and "thankyou for your service" bullshit that goes on, these are not, as a rule, either particularly nice or enlightened people.
We should not be surprised that a paramilitary civilian force resembles squad level army, at squad level.
There has, of course, been huge efforts to recruit from communities and at graduate level, but clearly the legacy remains.
I think the police force is, by nature, entrenched. They find themselves caught between a rock and a hard place in their daily operations, they need to be close knit, and they deal with horrible things on a regular basis that many of us never, ever have to see. Black humour is bound to develop, and I think that if there are misogynists present it can take a dark turn and become part of group culture. The police I know personally would be revolted by this, but I'm sure they would acknowledge its existence. Whistle-blowing cannot be easy given that the person on whom you are whistle-blowing might be a person you rely on in daily roles.
In which case the police force is not fit for purpose.
The armed forces are intentionally trained to find killing and violence acceptable in some circumstances. They seem like the least suitable people to be in the police unless their mindset is retrained from 'more violence, and force' being the solution to any given problem.
If the present police 'service' are incapable of creating a culture where lines very firmly drawn, can't be crossed by those in the ranks, then the whole thing needs to be overhauled, disbanded and reformed or whatever.
They won't be able to recruit decent people who wish to serve the public for all the right reasons
They won't have the consent, and trust of the public to be policed by them, particularly not the trust and consent of women, ethnic minorities, and other marginalised groups.
The whole system breaks down and we find we are under the control of racist misogynistic thugs.
Both those in our 'society' and those in the police 'force' too.
The fact that 'our' 'government' has cut funding to all the services which demonstrably cut incidences of crime before they even become a police matter seems to have escaped the notice of the populist press who are now screaming
"How could this ever happen?!?!?"
The same ones who will go on about 'woke' nonsense' when anything that seeks to tackle entrenched misogyny, racism homophobia and so on is implemented.
