I understand that it is very difficult to apply the ethics of normal civilian life to the realities of a battlefield and the rules of engagement in Afghanistan were as frustrating as they have ever been. The fighting against insurgents is particularly difficult as they don't wear uniforms to identify themselves and can more easily masquerade as ordinary civilians once they have stashed their weapons. Nonetheless, no one is above the law and that includes Special Forces.

Unpalatable as It may be, it is not just the bad guys who are capable of war crimes. I know that such groups are tasked with so called "black ops" that are technically illegal but we are talking about the possible killing of innocent civilians here. Surely an investigation is warranted at least? If these victims are found not to be "innocent" and those accused found to have had reasonable probable cause for their actions given the situation then I'm sure they will be exonerated. Had the same accusations had been levelled at Russian special forces I'm sure people would be more inclined to support investigations.
