Those are some numbers.
I think over here one of the ideas that someone had was to have neighbourhood watch things replacing local police (I think for things ranging from shoplifting to DV where the people can still be talked to/reasoned with somewhat and along those lines) and freeing up police for more serious problems.
I would be very pleasantly surprised if such a system was set up here and people did step up to go into it, my experience from every activity my kids have been involved with from homeschool groups to sports, there will be a literal handful of parents that step up and the rest will either genuinely be unable to help and usually be upset about it or will make all sorts of excuses about how they can't possibly waste their precious time
