I'm not the author of the book or the column. I don't know who killed him, but I'm certain it was not a lone gunman.
Certainly Oswald was working at the book depository.
Certainly Oswald shot Officer Tippet.
Certainly Oswald had been a marine.
Certainly Oswald had ordered a MannlicherCarcano rifle.
Certainly it was an easy shot to make 2 out of three times on a man sized target.
Kennedy was wearing a back brace, so he couldn’t lie down after the first shot.
