The police need to be in amongst the community.
It's like an over flowing water dam. In the old days the police would put their finger in the hole and contain the water. These days the police are in the dam using buckets to scoop the water out, meanwhile the water is still coming out through the hole. Probably not the best hypothetical example but the principle is the same i.e. the flow of crime will always increase if its not being stopped at the source, in this case the community.
Some serious questions need to be asked about the whole criminal justice service. The Judges for not sending people to prison for longer. The CPS for not charging people "just 1 in 15 reported crimes result in a charge". The police for not properly investigating crimes.
.
Judges have to follow the government's guidelines on sentencing and give explanations for why they've chosen the sentence they have, including the full reasoning - which includes things like mandatory reductions due to guilty pleas, or where they've chosen a fine and community sentence rather than a custodial one because the government has warned them there are not enough prison places available (IIRC at one point a couple of years ago some areas were basically out of spaces). Oddly enough cutting prison places and increasing sentence lengths has an effect on availability of spaces for new convictions.
The CPS are struggling as they're basically not funded sufficiently to do the job even for serious crimes, and the whole justice system is falling over due to lack of funding yet being expected to do things like go paperless when the courtrooms haven't even got sufficient sockets to charge the tablets/laptops the government requires them to use (but won't pay to maintain). let alone things like reliable fast internet connections and IT backends that are required to go fully paperless.
The "just 1 in 15 reported crimes results in a charge" sounds bad, but will include things that are not found to be a crime upon checking (IE someone reports speeding in their village but no evidence, or complains about something and the police check and find out nothing illegal happened), and things where the crime is reported but there is nothing to go on.
For example I had someone try and break into my house (and according to the police there were additional attempts in the same time period on neighbouring streets), the police came out*, they sent along a soco but there was nothing to find, the guy had worn gloves and my description was basically "about 6 foot tall, dark hair, jeans, looked odd wearing a dark puffer jacket given it was quite warm".
It will also include all the "nonsense internet crimes" (threats online etc) that I know some of the same people who call for the death penalty for virtually any offence love to mock.
Things like getting the intelligence from communites, back in the day, the council used to have money to run things like youth clubs which directly impacted low level crime as it gave youths who'd otherwise be bored and wandering the streets a place to go, and the police would often make an effort to get involved a bit with those clubs so that they had an idea of what was going on and they could be seen a being there to help, not just as someone you see when your mate gets nicked for being drunk, or you call when your car is stolen.
Oddly enough cutting back on policing etc because "crime has been dropping" tends to be a great way to reverse that trend, IIRC various very successful schemes to reduce crime were cut when "Austerity" meant the police had their funding slashed and all the "non front line officers" were sacked leaving the front line officers to now spend more time doing paperwork. I'm fairly sure I'm not the only person who remembers the obvious lie about "we're not cutting frontline officers, only the excess so it won't affect policing", as it was clear straight away that if you got rid of people whose sole job was do to the specific paperwork needed to support the officers, you'd end up taking officers from the street to do that same job but they'd be doing it slower, more prone to mistakes and costing more because they'd be doing it irregularly as opposed to constantly and the officers were paid more than the office staff.
*I was actually really impressed, they were here within about 30 minutes, apparently they'd been heading my way because of the number of reports.
