“the simplest explanation is usually the best one.”
I love Occam’s Razor, however, Oswald could not made all the shots, especially the one that EXPLODED JFK’s brain. That was a different bullet than the other shots.
Another thing to consider, who benefited by the JFK’s murder?
Follow the money.
That is where the lone assassin - Oswald - hypothesis falls apart. He alone could not have done the shooting.
The shots were easy to make.
I was a full ‘conspiracy’ advocate most of my life, reading 6-7 books, visiting the site and seeing all the movies. I finally read Bugliosi’s massive book three years ago. He convinced me it was Oswald. He addresses both of the reasonable points you two have made.
