Win!
Modern ballistic tests have shown that all the damage done that day is consistent with LHO's shots. There is no "magic bullet". That myth was started with misunderstanding of the limo seating arrangements and one misleading view of the recovered bullet.
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.
