- Explosive projectiles and 21 grenades found during a raid in Guadalupe
- An unexploded grenade and pull ring used to attack a TV station in Monterrey
- Automatic weapons, including U.S.-made M16s found at a cartel crime scene in May 2009
- U.S. military-issued ammunition found in a cartel raid in Reynosa in November 2008
You can't buy this stuff at a U.S. gun store. So where do the cartels get it? According to leaked diplomatic cables, there are three sources.
1. U.S. Defense Department shipments to Latin America, known and tracked by the U.S. State Department as "foreign military sales."
2. Weapons ordered by the Mexican government, tracked by the State Department as "direct commercial sales."
3. Aging, but plentiful arsenals of military weapon stores in Honduras, Guatemala and Nicaragua.
I didn't think you could pick up RPG's at the fair grounds.
Considering a good number of the cartel gunmen are moonlighting Mexican Army, driving their duty vehicles, it makes sense they'd bring their duty weapons too.
