For those few who might not have heard of the theory:
Secret Service Agent Hickey may have accidentally discharged his AR-15, causing the fatal head wound.
I am a newbie here, and certainly not even close to being as informed as many of you here, but I have read several books on this subject, watched probably every bit of video on youtube, traveled to Dealey plaza myself a couple years ago and of all the theories out there, this one made the most sense to me personally, but few seem to believe it. So, for purely my own peace of mind:
I would love to hear any facts that might disprove this theory.
For obvious reasons, please refrain from any testimony from any secret service agent, or FBI agent, or CIA agent, but all else would be greatly appreciated.
I will add that there are a few things about it that bother me, but the most significant might be the third shell casing found on the 6th floor that had a dent in it, so as to be used for a "chamber plug" . So maybe that is a good place to start?
