A quick googling of that quote turns up results from WingNutDaily, Breitbart.com, and Free Republic, but according to economist John Lott that is something Obama has said. (Although I should note he has authored books like More Guns, Less Crime and The Bias Against Guns.) The quote, if it's legitimate, is from 1996 anyway, so he obviously could have changed his mind since then.
I love it when I see things that say that "THE FIRST STEP GOVERNMENTS TAKE TOWARDS DEMOCIDE IS GUN CONTROL" and things of that sort. Yeah, because not letting everyone and their dog have a god[darn] tommy gun is obviously a sign that FEMA is building concentration camps to dump True Patriotic Americans™ into.
