I had not heard the AK47 had been already traced by the ATF back to the Mexican police.
Do you have a link to that info?
That’s huge: a weapon in the hands of an unstable man who got it somehow from the Mexican police ends up assassinating National Guardsmen and others in Carson City, Nevada.
So far all we have are multiple statements on the net ~ as comments ~ but it’s just a matter of time and we’ll find out. Issa should probably ask that question.
