The original Minutemen were an armed group of men ready to defend their country. The gave their lives for their country.
The Minutemen currently watching our border may be giving their time, but aren't giving their lives nor are they armed to defend their country. They are more of unarmed reconnaissance.
When you take an image of the original armed Minuteman and take away the weapon and add some binoculars and a cell phone on the Minuteman's hands, that somewhat smears the image of those true Minutemen that truly were ready to defend their country.
My advice to the Minutemen today is to drop their current name and call themselves what they really are; Border Watchers, Border Recon, or something like that.
If the Minuteman Project want to be a non-violent group then that is their choice, but who says that those illegaly entering into our country aren't violent and armed? A cell phone isn't going to stop the armed drug smuggler entering across the border and the time the Border Patrol responds to some call from a Minuteman member, that unarmed Minuteman member can be already killed by the armed drug smuggler trespassing into the U.S.
As far as a truly effective border guard, then you would have to be armed as you may have to use force to stop someone from illegally entering. But since our government doesn't use our, What do you call those guys again?, Oh, yeah, NATIONAL GUARD, to, uh, ummm, GUARD our country, then I can see where many citizens do want to take up arms to do the job that our own government and armed forces aren't taking part in except for a few border patrol agents covering thousands of miles of U.S. border.
I suppose if you want our government to place our own armed forces at our own borders then you may have to put a small, foreign, Islamic, oil producing, middle-eastern country there.
