Well the Taliban and others are armed to the teeth with AK47's too. I guess the USA supplied them with those also. Yeah, the rpg's too.
The US consistently asked for the serial numbers of the guns taken off the dealers and cartel soldiers. Mexico refuses. Ever wonder why?
For one, the USA is not to blame. Second, alot of the weapons were sold from the USA to the Mexican Army. Which in turn via corruption sold them to high paying dealers in their arms black market.
Now that's not to say some weapons didn't make it from the USA, but in reality the number would be in the low end single digits on a percentage scale. They're making it seem the USA allowed loaded trucks with Automatic machine guns by the tens of thousand to flood Mexico. That's absurd.
Also the spin given to it is specifically designed to further the agenda of abolishing our 2nd amendment rights.
