The irony is that Stanton is suspect in the assassination of Lincoln.
Say what?
That was the idea behind the David Wolper documentary, They've Killed President Lincoln!, in the 1970s. The theory goes back further to Otto Eisenschiml's 1937 book, Why Was Lincoln Murdered. Supposedly, there were pages torn from Booth's diary that would have supported the theory. No real evidence has turned up, and historians don't accept the theory.
