There were certainly incidents during the war in Vietnam, as there were in Iraq I and have been in Iraq II. To me, and to most Vietnam veterans, it is unfortunate that individuals such as Mr. Calley never got to serve the full sentence awarded by a military court, but rather were freed by politicians. However, Calley's murder of innocent civilians did not reflect official (or unofficial) policy in Vietnam, and the incidents which have happened, or allegedly happened, in Iraq are certainly not typical of the behaviour of the US and it`s (sic) forces of war on the whole. The unit I commanded in Vietnam never harmed a noncombatant...but we did provide expended artillery ammunition canisters to the locals to use in constructing a water pipeline. Civic action was as much part of our mission as combat, as it is today in Iraq.

Remember, accusations are not convictions. Personally, I'm willing to wait before blaming possible innocent people.
