Fair enough. Your post does back up Sober's point as he was only speaking of Oregon and no listing of such is found.
And to be fair, I'm not surprised that there are cases however I don't think there are enough for either side of the gun debate to make an issue of it. For the most part I find both sides of the gun debate typically hysterical and mostly irrational.
I believe in true egalitarianism when it comes to guns in that everyone should be able to be equally armed to one another. The State agent carries a pistol, everyone should be able to carry a pistol. State agent carries a bazooka, everyone carries a bazooka. Here's my favorite, the State has a nuke, EVERYONE gets to have a nuke.
One insanity propels the other and I'll let you figure out which is which.
