Thanks for posting that. Are the Minutemen actually armed? I'm not sure, because I've heard conflicting statements regarding weapons.
Personally, I don't see a problem shooting back. I do see a problem with our government allowing citizens of another country being able to commit an act of war against US citizens on our soil.
Of course, smugglers bring so much good to our country, it wouldn't be right to interupt their activites. /in your face sarcasm...
