Chaos ensued after Oswald's first shot through the back of Kennedy's neck. I believe THAT is when the SS agent's AR-15 was drawn and possibly fired by accident upon lurching of his vehicle. It is also likely surrounding SS agents heard that shot but there was no way the SS was going to admit firing the fatal head shot, even though accidental.

Yes it is UNLIKELY but it is POSSIBLE.

Sorry to differ with you. Why would anybody consider the SS agents behind the limo being involved in the plot? The agents drew their rifles only after JFK was down and finished. Look at the Altgens photo from the front. JFK is hit and 2 agents are looking at the TSBD while the other 2 (including Clint Hill) are looking forward at the limo, nobody is reacting except the Connolly’s at the Kennedy's.

The photos we see of the rifle drawn is only after the pass the bridge on the way to the hospital. We have to stop looking at bizarre theories and look very closely at who LHO was, who Ruby was and who gained from this tragedy.
