Not to nitpick but do you have a source for officials saying that WMD's were found in Iraq? Obviously US officials said that intelligence pointed towards Iraq having them, but I'm not aware of any statements like "we found chemical weapons in _____."
Edit: Based on the downvotes I guess this appeared to be nitpicking, but if we're going to use Iraqi WMD's as the canonical example of why we can't rely on statements from the government, seems like we should make sure we don't change the facts to fit a narrative either.
