The Smallest Minority is a definate stop if you're looking for facts. He's done the work that I, for one, am generally too lazy to do and dug up lots and lots of facts about guns, crime and self-defense. And he's done a good job listing cases showing just how far down the drain Great Britain has gone.
Another good one is Kim du Toit. He's currently on vacation, but has lots of past posts, and Gratuitous Gun Pics, and links to other folks.
Yes, I'm posting a bunch right now. It's been a long and busy day.
