The defund police advocacy wasn't really anything of note until George Floyd. You are saying the same movement that caused a reduction is the exact same movement that stopped the reduction? Also George Floyd was in 2020, a few select cities making some minor moves for a few years doesn't make up for decade after decade after decade of rampant expansion of police powers and armaments across the entire nation. I don't see any significant reduction in our prison population despite the consistent drop in crime, a prison population that dwarfs basically most of the rest of the world's prisoner-to-population ratio other than a few small countries that are either notably oppressed or completely politically unstable.
> You are saying the same movement that caused a reduction is the exact same movement that stopped the reduction?
Yes. Though there were two movements, a criminal-justice reform movement that went too far with e.g. bail reform. And “defund the police,” which was mostly attention-seeking behaviour that animated a backlash.

They’ve been falling for years [1]. Particularly in state prisons.
By your own source, yeah incarceration rates dropped for a few years, but are still over 5x as high as it was in the 70s, and is now on a sharp increase again. None of that is encouraging in any way or makes me think police powers are anywhere near a reasonable level or have been curtailed in any meaningful way. There are only 4 countries in the entire world with higher incarceration rates, and being anywhere near places like Rwanda and Turkmenistan is completely absurd.
