Suppose whichever police force(s) you're talking about shall be disbanded. In this experiment, you can choose some amount of delay between that announcement and the actual disbanding; whatever seems most reasonable to you.
How would that play out in the following days / weeks / years?
How do you think individuals, companies, insurers, etc. would adapt? What aspects of life would be better, or worse?
(Personally, I think society would be for worse off. But of course I'm only guessing, and could be wrong.)
