Just read more than 20 bullets hit them. It certainly wasn't the US soldiers intentions to capture them.
Given the trigger-happiness of the US soldiers, it's no wonder.

The US soldiers killed allied soldiers in friendly fires, but there are no cases of for instance british soldiers killing US soldiers in friendly fires. (There are very few accidents involving british among themselves).

John Simpson witnessed that too.

And here.

Why is that? Part of the US culture? Lack of good training? Lack of self-confidence? No fear of being prosecuted as they're just following orders?

About showing the bodies on TV: this destroys all the arguments used against Al Jazeera when they showed POWs on their TV.

All this occupation created bitterness for all kinds of reasons.
