Acquilla Clemons. Before the first shot, she observed two men standing near Officer Tippit's police car. She saw one of the men with a pistol, waving away the other, as he trotted toward Jefferson Street on the far side of the block.
The running man, the one she recalled as having shot the police officer, was in her words "kind of short, kind of heavy." The second man she recalled as tall and thin, wearing a white shirt and khaki slacks clothing which no other witnesses recalled Oswald wearing that day. Clemons said Dallas police officers told her not to tell anyone what she had seen lest she be killed, a familiar piece of law enforcement advice in Dallas that day.
Ah well that must settle it then. Forget the other witnesses who saw Oswald either a) shoot Tippit, or b) Oswald walking quickly from the scene with his gun in his hand. I would dismiss their testimony out of hand.
I would also dismiss immediately the forensic evidence that tied the bullets recovered from Tippit's body to Oswald's gun (to the exclusion of all others). Hearsay really.
This is Conspiracy Theory 101 - debunk and nitpick minor parts of the chain of events, but fail to provide an alternative.
So the floor is yours.
If Oswald was innocent, or framed, or both. What happened? By whom? In what order?
Go for it....
