How much of the police's time is taken up doing non-crime related activities?
That depends how narrow your interpretation of crime avoidance is. And how well informed you are on what they do, actually, do.
Schools
You think teaching kids that the police aren't the enemy, and building civic bonds, is a waste? You think establishing community policing with the people most at risk of committing public order and petty crime offences is a waste? Are you serious?
Cycling proficiency
Oh dear. Where to start: well, firstly it no longer exists and hasn't in a while - Bikeability does. Secondly, it has nothing to do with the police. At all. It's a Department of Transport administered scheme using accredited training providers. You might as well ask if the police should run driving tests, too. (For clarity - they don't do that, either.)
Postcoding bikes
As above, you appear to misunderstand something here. The database is police APPROVED. Not police run. It cuts crime via deterrence, this scheme, which is sort of handy, plus helps reunite people with their bikes easily and simply, with zilch police input, which cuts police costs. But again, it's not a police scheme, so your point is moot.
Desk jobs
You imagine that admin isn't necessary in a huge organisation? What, HR, record-keeping, reception, the myriad of other roles that exist in all major employers can be done by fairies? Not to mention statistical modelling and data keeping to track patterns - fairly important in lots of roles, but fairly key in crime, surely?
Admin work
Please see above. It's part of the same point.
Custody roles
Um. You don't think the police should arrest anyone? Have anyone there to book them in and out and keep tabs on them while in the cells? That they should have the power to deprive people of their liberty and not have to care for them, or record it, in any way?
Is that a joke?
Also utilised daily in things that other sectors should be dealing with (e.g. social problems, at risk children, people in mental health crisis, problem drug users etc)
You do realise the police are involved in such situations because they van be extremely volatile ones, and there is a need for police presence as backup sometimes, or to assess a situation and contain it while the appropriate professionals are involved and can assess? Because the police have powers that random members of the public don't, and they can therefore ensure the safety of the public, and that would include vulnerable people in crisis? How on earth is that a waste? That's not waste. That's need.
They said everything that is happening would happen. She sneered at them and said they were scaremongering and crying wolf. She was Home Secretary. This was her patch. We now have police roles filled by the army, which is something else she was warned about.
Corbyn put tens of thousands of new police in his manifesto BEFORE this all happened. Funny, how nobody is targeting him for being weak on law and order - just for a shoot to kill misrepresentation that the BBC news team were formally rebuked for, by their own Trust. Oh, and lies that he sympathised with the IRA. The Times published an apology for that claim as long ago as 1987, acknowledging that the police had confirmed he'd reported a suspected PIRA member to them. Then there's Ian Paisley's words commending him for his determination to talk to both sides, to help reach a negotiated settlement. Sort of what John Major very laudably did, which resulted in the Good Friday Agreement - no?
Is 'More Police!' the right answer?
Yes, it is.
Or is it more nuanced than that?
No. No, it isn't. You can't have a police force without, you know - police. Rather like you can't teach kids without teachers; something else they can't quite comprehend.
Theresa May has royally fucked up, and the chickens the police warned her about are home to roost. Right now.
