Idiot! He has threatened members of a foreign military.

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.

What does Arizona law say about the right to self defense?

In my state you can't shoot someone unless they are in your house.

This guy may be morally right but still end up in prison.

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.
