Not sure why we are talking about accuracy(?) all of a sudden, but goes without saying that I am talking about actionable convictions where the party is guilty, given based on facts and without prejudice.
My main point is people who commit certain severe crimes (think about serial killers, raping children, mutilation, premeditated murders/arson/lying in wait, etc.; these people should remain behind bars for all eternity. That's just my opinion; I can't imagine going to the families victims and telling them "dont worry, they will be good in a couple of years, and will get to live their lives thanks to our tax dollars, while your son/daughter rots in a grave".
There's no justice, no humanity in that.
