Border fence? We don't need no steenking border fence!

You know...because it's just hard-working Mexicans who want to do the jobs that Americans won't do:

A U.S. Border Patrol agent was held at gunpoint Sunday night by members of the Mexican military who had crossed the border into Arizona, but the soldiers returned to Mexico without incident when backup agents responded to assist.

Agents assigned to the Border Patrol station at Ajo, Ariz., said the Mexican soldiers crossed the international border in an isolated area about 100 miles southwest of Tucson and pointed rifles at the agent, who was not identified.

Well...this is just an isolated incident, right? A mistake perhaps by confused Federales who left their compass back at la officina?:

It was unclear what the soldiers were doing in the United States, but U.S. law enforcement authorities have long said that current and former Mexican military personnel have been hired to protect drug and migrant smugglers.

"Unfortunately, this sort of behavior by Mexican military personnel has been going on for years," union Local 2544 of the National Border Patrol Council (NBPC) said on its Web page. "They are never held accountable, and the United States government will undoubtedly brush this off as another case of 'Oh well, they didn't know they were in the United States.'

"It is fortunate that this incident didn't end in a very ugly gunfight," said the local's posting.

Fortunate? Mexican military invading sovereign American soil? Isn't that, like...an act of war? Maybe we can have a few helicopters ready to fire a missle or two the next time a foreign military unit invades our territory...

Or am I racist for even thinking that?
