It's actually been going down since 2008. The little table down the side shows the rate; it peaked at 0.75% in prison in 2008, and since then it's gone back down to about 0.53%, about 1992 numbers. 1980 through 2000 was when it shot through the roof starting from a level that was actually kinda reasonable.
0.53% is still way, way too high. It's unconscionable for a country that has enough wealth to be a paradise for everyone. Keeping it going down sounds great. There's a bunch of things to work on to fix it; eliminating private prisons, drug legalization, and funding the societal fixes (reduced wealth inequality being a big one) that reduce the number of people who are desperate enough or broken enough to commit actual (i.e. non-drug) crime.
I don't think "fuck the police" belongs in that list of how to fix it, though. Honestly I was just trying to say that that whole logical construction about how the police put people in prison and so etc etc QED they are bad was a big oversimplification, to me, and so it's gonna lead people away from talking about more complete solutions and a complete understanding of the systems and where the problems are. Not trying to say there are no problems, because there are problems, yes, 100%. We may disagree on the scope of the problems and the police's role in the problems but yes, absolutely, there are problems and injustice rampant in the US criminal justice system, on that we can agree.
