The only result of “defund the police” movement so far has been an explosion in violent crime. The murder rates skyrocketed in 2020 https://www.nytimes.com/2021/09/22/upshot/murder-rise-2020.h...
Any stats about a rise in crime is very misleading. The cause of the rise in crime is in no way related to systematic policy changes in funding because there have been no changes made.
It means different things to different people. Some want to literally abolish police, some want to reduce funding.
