Behind The Scenes With John Walsh Across The Mexican Border

There's a war going on within Mexico's borders: more than 40,000 Mexican military troops are stationed all over the country in an effort to fight the destabilizing threat of extreme violence fueled by the drug trade.

For many Americans, it can seem like a far-off tale in a distant land. But each day, the danger hits closer to home as more and more American communities are experiencing the effects.

Their illegal exports -- ranging from crystal meth and cocaine to heroin, marijuana, and everything in between -- stream across the border, and Americans can't seem to get enough. It's Americans that fund the cartels' private army and fuel the deadly struggle for power.

America's Most Wanted host John Walsh went across enemy lines to investigate the scourge of Mexican law enforcement that is spilling across our border with increasing regularity.
 
Not even an enormous fence along the Mexican border can seem to make much of a difference.

"There are about 15 attempts every week to cut through that fence with portable saws and portable blowtorches," John said.

Despite the heavily-guarded border, the drug runners are able to create distractions or even attack border guards.

"Somebody will cut the hole, 20 people will go in, drugs will go through, and try to deter them from catching them on the fence," John said.
