Please define "sensible" civilian gun control in the US and explian how it will prevent criminal gun use in Mexico? Fact - Civilians in the US cannot leagally own M-16s or any other fully automatic weapon without a FFA licence.
Sweet! I am a country boy cum suburbanite and I have a couple of pygmy goats as pets. That ought to get me an FFA license, no?
Kidding aside, you are spot on. Without passing a lengthy background check and other steps, including a federal tax, one cannot easily purchase automatic weapons in the US. Furthermore, thanks to the unconstitutional Hughes Amendment to FOPA, the prices for transferable automatic weapons are artificially hyper-inflated. Mexican drug gangs can buy automatic weapons far cheaper from every source but the heavily regulated US.
