You keep ignoring the fact that saint Oswald tried to shoot a police officer when being arrested. This all but proves he shot JFK.
Did he? We only have the word of "do you want my autograph" McDonald for that....
And how does that prove he shot JFK? How in the world did you come to that conclusion?
Let me put a hypothetical to you. What if Oswald was involved in a plot which purpose is to kill Kennedy (but he doesn't know that). He's merely a foot soldier at a very low level and when Kennedy is actually shot and killed he understands the position he has been placed in and panics. He runs to the Texas Theater because he has been told to go there in case of trouble and he finds that his suspicion is correct. Instead of a contact showing up, the police are there in force. So, in a desperate attempt to get away he pulls his gun.....
Don't tell me this isn't a possible scenario! How do you reach the conclusion that he killed Kennedy?
