I got a bit closer to the law than usual over the last few days and while my service was brief and didn't actually involve any kind of service I was left wondering after I read this at reason.com. That we find an awful lot of men behind bars is not all that unusual. Most bartenders I've met are men. That we have so many men who have been sentenced to prison for crimes they never committed is a failure of the people. If you read the story at the link, it briefly mentions some of the corrupt practices that led to what amounts to lifetime sentences in jail because somebody managed to fool the jurors a lot of the time.
I think that defense attornys should be given a special allowance at voir dire proceedings to eliminate the people who are too stupid to listen to the facts of the case and too stupid to make up their own minds about a person's guilt or innocence. Believe me, I have seen some really stupid potential jurors and you don't want them with your fate in their stupid little hands.
