Beginning this Wednesday, the entire 2,000 miles of border between the United States and Mexico will be patrolled by unmanned aerial drones. Three drones are already patrolling portions of that border, and a fourth Predator begins operations tomorrow out of Corpus Christi, TX, completing the full stretch of la frontera.

The news came in a Department of Homeland Security announcement yesterday, along with word that 1,200 additional National Guard troops will be deployed "to provide intelligence surveillance and reconnaissance, and immediate support to counternarcotics enforcement."

Those Predator B drones are made by military contractor General Atomics. You can read more about the drone specs here at the General Atomics website, and download a PDF here. Snip from Reuters:

They carry equipment including sophisticated day and night vision cameras that operators use to detect drug and human smugglers, and can stay aloft for up to 30 hours at a time.

And a major drug kingpin nicknamed "The Barbie" for his light complexion was arrested this week— his takedown is seen as a badly-needed public relations coup for the Mexican government, as successive waves of horrific news hit the country.

Perhaps the most gruesome of those recent revelations was the discovery just last week of a mass grave filled with 72 murdered migrants, including a pregnant woman, who were all executed by a dominant cartel, the Zetas.

The incident took place just 100 miles from the US border.

From the Christian Science Monitor:

The massacre confirmed what analysts have begun to suspect (....) gangs are diversifying their criminal activities and targeting groups other than just rival drug traffickers.
