Most Americans think of our neighbor to the south, the land of Meh-hee-ko, as a place primarily populated by taco-wielding mariachi bands passing out tequila shots in a welcoming spirit of friendship, speaking "espanyole." We regret to inform you that that impression may be overoptimistic.

The WSJ reports that for the first time since this little Neverending Drug War began, the U.S. government has posted an official warning that "Mexican criminal gangs may intend to attack U.S. law-enforcement officers or U.S. citizens" in certain parts of the country, including Tamaulipas.

But hey, the 116 bodies found in the Tamaulipas mass grave this week are Mexicans. It ain't so safe for them either.
