"Armed foreign military on his "ranch." A foreign military doing an illegal incursion into the United States and threatening his life and property. Hmmmmm...he may have probable cause.

Nope. The courts aren't going to see it that way. He's announcing in advance that he's planning to shoot a member of a foreign military. If I remember right, the actual border is not all that clearly marked there. He's blowing hard, of course, and is unlikely to actually carry out his threat. If he does, he may not even survive to face trial.

I still maintain that he's an idiot.

The border is very well marked at that location.

The border is marked by the Rio Grande for Texas, although you could argue ignorance of geography. If the bad guys shoot first he has every right to defend himself.

Yes, the authorities could arrest him for PC reasons, but if it's a trial by his peers down in Texas, I don't see them convicting him if he's in the right.

In the event of an invasion of a foriegn military, I'm damned glad I won't have to rely on you to watch my back.
