Dude, first off, do you honestly think the Iraqi's were running over to make sure any possible US soldiers inside or nearby were OK? Do you think that they wanted to run over and wrap them in bandages and make sure they didn't hurt anymore? Or were they going over to quickly claim any weapons/intelligence and return them to us so bad people didn't steal them?
No, they wanted to loot the shit out of the vehicle and there's a good chance at least a couple wanted to capture and torture any disoriented or wounded Americans they might find nearby(not saying there had to be some nearby but likely the Iraqi's didnt know that for sure).
Not everyone, or even close to everyone, in Iraq, are innocent buddies of the US.
Here's a similar scenario,
"A gun store owner just realized he forgot to lock the safe inside his store and he notices a bunch of people that just escaped from jail and are still wearing their orange jumpsuits(but might turn out to be friendly dudes, who knows???), running a bee line right to it.
What do you think he's going to do? Politely ask them in a language they don't even understand to please not take any weapons, and if they must take some weapons, be sure not to use them on him?" Yeah....that's what i would do...
