I will admit that I am late to the party and have not read all of the posts on this yet. Regardless, does this matter at all? Does this change the historical fact that Lincoln did die from the wound of an assassin? How does this advance our current knowledge or adapt the interpretation of the recorded events?

Of course it does not affect any of this. There is really no scientific merit to this at all. Perhaps the tag should be "what if" rather than "science."

Let me be noted as the first person to state that my death could have been prevented with the technological advances available in 140 years from now! I will gladly accept my great posthumous honors in advance for this amazing "discovery."
