"A neutral group" would be a very good idea. But it's not an idea that is going to be entertained by the current US administration.

The UK military and Government of course know that in principle they are subject to the International War Crimes Tribunal. It could be that this is a factor in what appears to be a less questionable human rights record in Iraq than their colleagues from the States. (After all the record of the British in colonial and similar wars has at times been pretty dire.)

Once again, there is no question about "If there has been a coverup" - that's been admitted. The details of who was responsible for the coverup, such as who authorised it, who knew about it, and why it occurred, that's what the investigation is apparently geqaring up to tell us. But the fact that there was an attempt to deceive the media and the world with a lying version is not open to question.

And we've still to find out whether this is a genuine investigation or a Widgery.
