Watch the winshield. It is struck by a bullet.
That sequence is from the DVD with the four digitized sequence on the assassination.
I did not go into the earlier shots as the two shots at the end alone prove conspiracy, you can see Connally shot in the Zapruder film, the Dallas Police recording recorded it, and the witnesses said they heard BANG-BANG.
Since they all say essentially the same thing, a resonable person would conclude there were multiple shooters.
