I don't think so. Oliver Stone has had a very curious obsession about this for many years. Do we know where he was at the time?
Stone also probably had a double to confuse the track. To my knowledge, Michael Moore has never accounted for his whereabouts either, so all we need to do is prove he's been lying about his age as part of the coverup.
QED
The only thing I can swear to is, I know where I was at the time and I didn't do it.
