the US will be nice and try to avoid killing these people. we will try to shoot around them, indirect fire behind them, get them out of the way, etc.
the iraqis will just shoot them, mortar them, etc, and blame it on us for their propganda machine.
europe, the press, and the US blissninnies will believe iraq, making it harder for us to finish the job due to a drop in public support; afterall, iraq would never kill people trying to stop the US's war, would they?
