There was a entry over at antiwar.com by an Iraqi-American from the Minnie area, who owns the ME restaurant Sinbads who visited Iraq and mentioned things like this occurring. Only he went further and said some US Marines were shot at by men driving American vehicles, who spoke perfect English. He said they wore masks. I don't how true it is but this story seems to give some credence to it.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
