I remember reading a statistic that noted that all the guns in Australia that were purchased as part of the buy back scheme (in addition to implementation of gun laws); would only make up about 2 weeks of US NEW gun purchases.
Just the amount of new gun purchases in America is mind-boggling.
Yep. The sheer size is daunting. Heck even if you grandfather in previous registered owners and stopped selling new guns, you are talking about a couple of hundred million registered guns out there. That will last a few generations.
