There are lots of myths floating around. You've all heard them. Things like "13 children are killed each day by guns" and "accidental gun fatalities are a serious problem" and "guns are not a good deterrent to crime" and "most Americans favor gun control".
If you subscribe to any of these myths, or lots of others, you should rush right over and grab a PDF copy of Guy Smith's book, Gun Facts, available from his website of the same name. If you run into other folks who subscribe to these myths, you should grab it, too. Heck, just go get a copy and read it. It's worth the time.
