Why do these idiots keep pushing this shit when it is so obviously composed of complete and utter fail? (http://www.cato.org/dailys/05-13-00.html)

What's wrong with requiring background checks before the purchase of a firearm?  Would it not make the distribution and tracking of that firearm more reliable?  And that 1% statistic, are there further reports to support it?

I ask because I really want to know.  Someone please convince me, because I really don't feel that the inability to buy a weapon at a gun show equates to a denial of my 2nd amendment rights.  I can still buy a gun at any number of places, right?
