Army National Guard overrun at the border? Well, they retreated, anyhow:
"U.S. Border Patrol officials are investigating the 11 p.m. Wednesday incident and trying to determine who the armed people were and why they approached the post near Sasabe, in the desert corridor between Nogales [Arizona] and Lukeville. Balaban said the troops didn’t know how many people were involved because it was so dark."
What? No night-vision equipment? It would be interesting to know why the guard didn’t stand and fight.
UPDATE Well, it turns out that "very few" of these Arizona guard folks are armed. The ones in Texas and New Mexico are armed, but "very few" in Arizona and California. That is remarkably stupid.
THE TEXAS SCRIBBLER 
This is pure lunacy, but who’s perpetrating it? Is it the Feds? Is it the governors of the states? Is it the local commanders? Someone’s going to get killed, and I pray that it’s not a Guardsman with an empty magazine, but that seems to be the most likely scenario.
More likely the politicos in the states. Even the Border Patrol carries sidearms.
