I love The Volokh Conspiracy.
For those unfamiliar, it is a legal blog hosted by a law professor. There are a number of other heavyweight legal types who contribute, thus the conspiracy angle.
It can get a little pedantic sometimes. And, sometimes they get wrapped up in minutia--but that's just showing the fun they're having. But, overall its a great site where you can learn a lot.
Plus, Volokh is on the gunner's side to a certain extent. He masterfully dissassembled an anti-rights argument a while back: http://forum.opencarry.org/forums/sh...cs-About-Guns&
