Wrong. The ballistics for the head shot are different, but in respect to the 3rd and fatal shot I’m not asserting a conspiracy with multiple shooters.
Rather, I’m projecting a well-established conspiracy that Secret Service conspired to cover up the origin of that bullet...one with characteristics differing wildly from LHO’s rifle rounds.
The secret service was known to have partied wildly all night long the night before at strip clubs. Wonder what club that might have been?
Totally hung over, they give an inexperienced, relatively new guy the new rifle, a Colt AR15. Remember Senator Yarborough and several others noted a strong odor of gunpowder immediately at ground level, at the underpass and all the way to parkland!
It was a tragic, one in a million thing, but there is a school of thought that a secret service agent accidentally fired the fatal head shot on the president. If true, it would explain quite a lot of things in the aftermath that defy explanation.
One of them being, Oswald. Maybe Dallas PD did the Secret Service a solid? Hm.
