I have always been fascinated by the opinions that the Supreme Court hands down when they rule on a case. You have to figure that these are some of the best and brightest minds in the country and they probably understand the law better than anyone around.
I do not have any training in the law myself and a lot of what gets said in those briefings goes over my head. Still, I can pick up pieces here and there and the more you read the more you begin to understand the logic that goes into interpreting the law. It's not always page turning but it can be fascinating.
