On another point, if headshots are considered evidence of execution, should we consider any Iraqi shot through the head to have been executed?

You obviously don't shoot much. And neither do the Iraqis. Getting headshots (5, no less!) with a Kalashnikov much past contact range would be quite a feat.

But something tells me that forensic examination would show the projos to be pistol caliber.

I saw some of the pictures and they weren't all headshots. There are clearly other very severe wounds.
