There is, of course, the whole bell curve of erroneous outcomes. But you can't know a priori who are the genuinely innocent people. The reason justice reform is so hard is because it's hard to get police and prosecutors to assiduously assure people's due process rights when the overwhelming percentage of people they deal with are bad people.
I think prosecutorial misconduct is absolutely unacceptable. But I can also see why it happens, without assuming that it could only happen if large numbers of prosecutors were evil people who would convict someone they knew was innocent just to inflate their quota.
Yeah, I'm not shaking my pitchfork, I guess I'm thinking there is an interesting discussion to be had about how you make a system that is probably pretty good 10 or 100 or 1000 times better.
Which is actually an interesting thing to consider when you are applying laws to millions of people.
(still, from where I sit, convincing people that prison should not be a hell pit is a much bigger win right now than sweating false convictions)
