The information is out there, Google is your friend.
Yes. And if you keep googling you will find many studies and articles that show exactly the opposite. One article on the web doesn't say much. I asked the question because while I was attending graduate school we were given loads of evidence to the contrary: guns cause crime much more often than prevent it. The U.S. has the highest rate of violent crime of any country in the first world, that lack of gun control means "x" times as much people die violent deaths in our country. Our lax gun laws mean our guns can and do easily go south of the border to support drug cartels and the heinous crimes they commit... etc etc. Most of this info came to me a decade ago, but as nothing has changed wrt gun control (if anything, access to guns has become even easier), I doubt those stats have changed much. But I honestly don't know and am not interested in proving my point enough to do so in this instance.

Anyway, I agree responsible gun owners exist, but I think too many guns get into the hands of the wrong people as a result of poor regulation and/or enforcement, and it would behoove us all to do whatever we can to change that.
