This is a great book debunking all of the anti's rabid claims. It is a free download. I have only skimmed through it but it looks like some very good and important information. http://www.gunfacts.info/
Excellent source of statistics you can use to counter distorted claims by the antis. If you use them, by all means go to the original documents cited in the bibliography and look for any disclaimers that can crop up and make a mess of your arguments. It is now on my hard drive for ready reference.
