We also massively increased reports of crime after the after the 90s, so it's no wonder there's more crime... because it's amazingly reported correctly rather than ignored.
The effect the supposedly Tory oriented policy line they've had for decades with respect to the police (that you know, they'd actually care about it's functional ability to police), while they've done literally the opposite. All the while their voters berate the police for doing their job as declared by the Tories in the first place, and it's almost as if the voters are dumb as bricks.
I'd bet a lot of money that the reduced Police numbers are to blame for any supposed increase in crime recently. Less officers means there's little lee-way for the officers that have to somehow function correctly, people get away with so much more because they literally can't stand there handing out a fine to someone while another more pressing matter requires them.
It's a cascade failure we're witnessing here and the Tories are at the heart of it, there's nothing more they'd love than to have a private police force at their beck & call, it's much too liberal to allow the plebs protection for "free".
