Several problems. It was not an AR 15 but a M 14. Big difference,
And if he had fired that weapon he would have blown out the ear drums of 2 Secret Service men.
Your comment #92 was completely rebutted by my citation from Menninger that there were many witnesses (see my comment #93) who saw agent Hickey armed standing in the follow car while the car was in Dealey Plaza.
Without citation, you now allege his gun was an M 14, not an AR 15 which is reported in Menninger’s book with pictures. Don’t intend to be mean or grind an ax with you, I’ll take Menninger’s book as correctly reported and consider your comment as inaccurate, factually wrong.
