A single bullet? Gracie K. says, "Probably not."

In the YouTube video titled "Beyond Conspiracy: Kennedy Assassination," Dale Myers explains everything to prove President John F. Kennedy and John Connally had been shot by a single bullet. Myers begins his explanation by going through an animated simulation of the Zapruder film. Meyers pinpointed every single bloody detail of the Kennedy assassination, including the exact setting of the incident, and the positioning of the shot men's bodies. He demonstrated that the two men had indeed been shot by a single bullet, because when the second out of three shots were fired, the two men had reacted from wounds simultaneously. The bullet had passed through kennedy's back, through and out his throat, and then entered Connally's back, and out his chest. I assume after that it had passed through his wrist and lodged itself in his thigh, because he had been examined and had bullet wounds in those places.
Honestly, I don't know who to believe. There's been evidence supporting both sides: the single bullet "fact," and the conspiracy theory. The third and INSANTLY fatal shot fired coudn't possibly have come from the Texas Schoolbook Depository, but probably from the fence by the grassy knoll to the right of the limousine. However, I'm not as thoroughly educated as those who have dedicated their lives to research on the Kennedy assassination, so I feel like I don't have the right to talk. Most theories are plausible, and incredibly probable. I'm pretty convinced there was no way however that the third shot that blasted the President's brain into several chunks could have come from Lee Harvey Oswald's rifle. It's unfortunate they're all too dead to share the truth with curious students like me.
