Defunding is an interesting view point, on one hand it could be extreme, which some people might think is stark raving bonkers, but on the other hand, depending how it applied, I think there is something within it, that needs looking at.
One of my arguments often with criminality, say where mental health is concerned as just one example, all the resource is chucked at it after an event, rather than before it, and by that time it can suck up all the financial resources, virtually for the whole of a county line in one incident.
Hospital treatment for the victims
Sectioning of the individual
The potential loss of life
Criminal investigations and trial that will run into millions
The assistance required to rebuild the lives affected
The list is endless. Events occur due to a lack of social support, or the lack of knowledge in how to obtain that assistance.
I sat on a trial of one such incidence, and when the defence asked, why didn't you do this, that and the other in the investigation, it was openly retorted, have you any idea how much time, resource and finances, one such incident takes to investigate. Basically the long and short of it was even if you had the money, the man hours involved were impossible to achieve the perfect evidence.
That's the cost of not dealing with problems within the community. Much like the lock-down, it's very easy to go into it, it's a damn sight harder coming back out of it, especially for the people it left behind.
You only need to look at the case of George Floyd, one dodgy $20 dollar bill, will now become millions. One life and millions of dollars could have been saved, if the cops hadn't bothered turning up.
