Further to my last post, I should point out that I am really not complaining about the individual soldier involved, but the US administration and it's failure to manage the invasion properly. I remember when the mission in question was to win the "hearts and minds of the Iraqi people". Then they launched a major offensive on the holiest day of the year. Can you imagine if a foreign government decided to bomb us on Christmas day? Would that win over "hearts and minds"?
If anyone was in any doubt that the situation in Iraq is now desperately out of control, that the US cannot effectively look after or control its own troops and doesn't have enough troops out there, try this article, which among other things mentions that the marine who shot the injured man "had been shot in the face the day before but had already returned to duty". When asked by his lieutenant if the man/men shot had been armed, the marine apparently shrugged. Draw your own conclusions.
