Ouch. That's gotta hurt.
We didn't have a boarder patrol in 1916. All we had was the army.
Pancho Villa had an army of his own. This is a small group of relatively well armed smugglers who MAY pissibly be tied to the Mexican Army, though it's doubtful their acts are sanctioned by the Mexican Army.
The Army is a horrible tool for investigating smuggling. They're good for fighting other armies, but the vast majority of the problems on the boarder are with civilians, and the army isn't trained to deal well with that, nor is it practical to call up the army to deal with rare incursions of small group of armed people.
We need to increase the size of the boarder patrol and equip them properly.
If there's a national guard base in the area, it would be good to keep a team or two of special forces ready to be called up on governor's orders to deal with things like this if we don't want to equip the boarder patrol to handle it.
However, comparing this to Pancho Villa is something that belings in one of Michael Moore's movies, not in a constructive discussion about the problem.
