That's what I said about understanding what the injustices really are. The challenge isn't as simple as what you're saying: "just don't charge innocent people." The challenge is getting prosecutors to give defendants their due process, even when the defendants have damning evidence against them, when they have criminal records, when they are caught up in shady circumstances.
I read an article the other day about a guy who was convicted of murdering a pizza delivery driver in front of his wife and kids. There were questions about whether he had been the one to shoot, but there is no doubt that he and his friends were in the process of robbing the driver when one of their party shot the driver.
I don't actually like the you're-guilty-of-murder-if-your-cocriminal-kills-someone rule, but that seems like exactly the sort of case it's intended to work with.
Although, he was re-sentenced to a 30-60 year sentence with possibility of parole after a 2012 Supreme Court case: http://www.thealpenanews.com/page/content.detail/id/624360/N.... Big victory for criminal justice reformers. :-/
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)
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.
Most might not, but some most certainly do.
