NYT's Thomas Friedman

This morning NYT columnist Thomas Friedman had this to say about Mexico:

The Narcos are the drug cartels who are now brazenly attacking each other in turf wars and challenging the state for control of towns. The success of U.S. and Colombian efforts to interdict drug trafficking through the Caribbean and north from Colombia have pushed the cartels to relocate their main smuggling up through the spine of Mexico. President Felipe Calderón is bravely trying to take them on, but the Narcos have bigger guns than the Mexican Army - most smuggled in from U.S. gun stores.

He needs to hear from us that the kinds of heavy weapons being used in the narco-wars. - machine guns, grenades, RPGs, etc. - are not available in U.S. gun stores.
