Bad Message
If this is even a halfway accurate version of the story, it says very bad things about our jury system.
The whole lot of them unanimously agreed to let all the mobsters off for all the crimes they obviously committed - not just a few times but as a way of life. Why? Because the con artist mobster cracked jokes, showed how human he was and convinced them he was just like them, the jurors. He talked about how much he LOVED all these guys. And the noble martyr BS at the end where he tells them to find HIM guilty (even though he's not, but he's used to it, he says) but free these other guys, that was so disgusting. The jurors had to be absolutely STUPID to fall for such garbage.
For the most part our jury system works. But as this story demonstrates, it is possible to come up with an entire jury of idiots, especially when it is anticipated that it will be a very long trial. Normal people can't stop everything for two years to sit on a jury. So they end up with dumba**es who have nothing else to do.
Very, very sad.
