But regardless- Booth was no soldier- as a citizen of the United States he was nothing more than a murderer. Or he could be considered a traitor.
The civil war was not really a civil war (since the south did not want control of the country), but it was an internal war and that makes it very tough to say who was
a traitor. THINK
Whether Booth was an ordinary murderer or a traitor really makes no difference to me.
