I have spent a lot of time studying this. When I taught forensics we would spend a month on this case. I think the evidence is crystal clear what happened. I am not interested in debating this or even discussing it anymore. Anyone who is contentious, the evidence is overwhelming and is all published.
Yes, there are bogus stories about what happened, but there is only one story that can explain everything that happened including the policeman who was killed, all the witnesses killed later, the autopsy, Zapruder film and the Warren Commission.
