please back up your claims with statistics. I'm very familiar with Mexico's gun laws. Perhaps you've mistaken Mexico with some other land. The country I speak of has been a war zone where drug cartels turn people into soup and put them on public display.
the legally owned guns in Mexico are few and far between, but when they can be pooled together things like this happen:

From what I recall, the "tourists" that were shot at didn't stop for the checkpoint.
If it's a numbers game you want to play, ban salt, sugar, and automobiles. Guns can't hold a candle to those death statistics.
