The trajectory not only works, given the relative positions of Kennedy and Connally, the angle of Kennedy's back wound and the angle of exit at the throat and the reconstructed trajectory, any bullet exiting Kennedy's throat on that path would have HAD to have struck Connally. There is literally nowhere else for it to go. (And the wound in Connally's back was elliptical, not circular; it was caused by a bullet that was already tumbling.)

I don't see any "unscientific" here except from you; you make assertions that are easily refuted by evidence.
