Question If someone, while operating a motor vehicle, mistakenly thinks he can drive by a pedestrian but unfortunately hits and kills the pedestrian, has a crime been committed? Answer Yes. The crime is called manslaughter, and people are imprisoned for this crime especially if negligence on the part of the vehicle operator is a contributing factor. Question If a President of the United States starts an unprovoced war because he believes that there is a threat against the United States and later it turns out that there was no threat and in fact the "evidence" of said threat turns out to have been poorly vetted showing negligence on the part of the President, is this not also a crime? Answer YES! At the very least Bush's War is mass manslaughter, clearly a war crime.
