The threat from Mexico

Crime groups in cahoots with venal army officers are looting military arsenals in Central America, giving them powerful weapons that allow them to outgun police and challenge the region's regular armies.

The weapons run the gamut from assault rifles to anti-tank missiles, some of which the U.S. supplied during regional conflicts more than two decades ago. The slippage from military armories occurs regularly.

The feared Mexican organized crime group known as Los Zetas has stolen weapons from military depots in Guatemala three times in recent years, Guatemalan Deputy Security Minister Mario Castaneda told an anti-narcotics conference in early April in Cancun, Mexico.

In February, U.S. prosecutors unsealed a five-count indictment against a retired army captain from El Salvador for allegedly selling or offering C-4 plastic explosives, assault rifles, grenades and blasting caps to undercover agents.

How long do you think it's going to be before these weapons start to cross our porous unprotected border with Mexico?
