Whack-a-mole drug war - Headless corpses spark worries on Mexico's southern border

A close-up look at the Mexico - Guatemala border -- or lack thereof.

Headless corpses spark worries on Mexico's southern border | McClatchy: "ALONG THE USUMACINTA RIVER, Mexico — If the border that separates the United States and Mexico is fairly easy to penetrate, then Mexico's other border — the southern one, abutting Guatemala — is virtually a sieve.

For a few pesos, boatmen along this jade-hued jungle river will take people or cargo across, no questions asked. On one recent day, rustlers could be seen driving long-horned cattle from trucks at river's edge onto waiting boats.

That's just garden-variety smuggling. Of greater concern are the tons of illicit narcotics that move north, and the drug cartel gunmen who move easily in either direction, committing crimes on one side only to escape to refuge on the other."
