"When conspiracies have governmental powers, they can usually cover up their guilt at the time and they often destroy evidence so thoroughly that later generations are left with a puzzle they can solve only partially or tentatively. We now know only that the assassination of Abraham Lincoln was arranged by a conspiracy for the dual purpose of eliminating a political figure who was no longer useful and of exciting fresh animosity against the Southerners who had been conquered, and whose country had been destroyed, in the unconscionable war of aggression of which he had been the ostensible leader; but, aside from a few hirelings, the only person whom we can positively identify as a member of the conspiracy is Stanton, who was the Secretary of War in Lincoln’s cabinet, arranged many of the practical details, and was able, after the event, to silence key witnesses, although we can only guess what it was they knew that made it necessary to have them judicially murdered. And Stanton seems to have been only a local manager for principals whose identity we can only surmise."
