A real world conspiracy to assassinate the US President.
John Wilkes Booth was employed at the Ford Theatre and collected his mail there.
Booth learned of Lincoln's attendance at the theatre that morning.....
The logic of the LN argument falls at the first hurdle.
A false example. There was not a conspiracy to use John Wilkes Booth to assassinate President Lincoln. And then, after Booth was selected to be part of this conspiracy, he fell into a job at the Ford theatre, giving himself the perfect opportunity to murder President Lincoln.
Also, it is possible that one of the reasons Booth first thought about kidnapping and possibility killing President Lincoln was that he knew that his employment at Ford?s Theatre might someday provide him with a perfect opportunity. He surely knew that President Lincoln sometimes visited the Ford Theatre. Had he not been a famous actor, he, like thousands of others, may have hated Lincoln but maybe would never have taken any concrete steps to try to murder him.
The assassins Booth and Oswald were similar to each other. Each were lucky enough to have the President pass by or visit a place they worked at or used to work at. The only difference is that Booth had enough fame and wealth to recruit others into his plan, making it a conspiracy. But both were fundamentally ?Lone Nuts?. Except Booth, after first becoming a ?Lone Nut?, was able to recruit others.
