(how's that for scary for you Bluke...I'm agreeing with you.)
some people believe there's a difference of opinion on this - but the facts remain that American troop now recognize that they're lives are in danger from apparent civilians (rather than uniformed troops). They're fighting gureilla tactics and are now taking what they believe are the appropriate steps to protect themselves.
And they are opening themselves up to world criticism in the process.
(Just wait till they run over a unarmed girl with a tank and see the criticism then!)
