Jacky killed Kennedy
After the shot, Jacky quickly withdraws her white gloved hand from her dark blue handbag, containing the special firearm, puts the handbag away behind JFK, and climbs in the direction of co-killer Clint Hill.
Normally a bullet doesn’t cause smoke; the barrel of a gun does.
But this bullet was filled with phosphorus, which burned its way through JFK's head.
The message to future leaders: DON'T MESS WITH THE JESUITS, THE POPE, THE CIA, THE FEDERAL RESERVE and the SATANIC ROMAN EMPIRE and LUCIFER!
