If they simply get in the way? No. If they start throwing rocks or shooting at the soldiers, then of course yes.
throwing rocks, it's a big deal unless it turns in to a big deal. You really think soldiers should be shooting kids when they are throwing rocks at tanks? (refering to the video that was posted a while ago). But if the kids were shooting at the soliders then yes, or if the rocks were hitting soliders and hurting then, maybe.
You also have to know that not everyone in the world speaks english, so if a soldier is yelling at someone to get out of the way in english and they don't understang, I don't believe shooting and killing them will help.
But I think more power should be put in the soldiers hands, if the soldiers feel threatened they should fire warning shots, and maybe use deadly force. I would rather have soldiers kill an unarmed civilian that wouldn't listen, or looked like they could've had a weapon or bomb, then a dead soldier because he wasn't sure if was allowed to shoot the person pulling something out of a bag that was a bomb.
What makes a soldier more worthy of living than an Iraqi that doesn't understand English competently? Nothing? In fact, IMHO, the soldier has less of a right to be their, due to many factors outlined in the other Iraqi debate thread, which i wont go into, unless you feel it is necessary.
If translators aren't going to be provided, then i think no blame lies with the Iraqi's.
[My post only applies, if the Iraqi's are harmless, and don't get out of the way]
I think it depends on the situation, but if there is a civilian standing by the road, I don't think a soldier should shoot him/her. But if there is a civilian that is running towards a group of soldiers with something that looks like a bomb or a weapon, then by all means shoot em' down even if you aren't 100% sure they have a weapon/bomb.
And with the language barrier, yeah, that could cause problems, and it really depends on the situation whether or not to use force. Like I said, maybe firing warning shots, because if someone is shooting at you, you aren't just going to stand there, or continue to throw rocks at them.
