Radley Balko writes about an issue that has always troubled me about the American judicial system. If you're accused of a crime, the way to get a lower sentence is to plea bargain…but to plea bargain, you have to admit guilt and what if you're not guilty? Answer: You may well do more time than if you just lied and said, "I did it!" Which among other wrenches of sanity means that the guy who did do it gets off scot-free.
