The magic bullet wasn't very magic when you take into account the seating arrangements. The jump seat in front of JFK was slightly inward and lower then the position JFK was at. Then also connally was sitting twisted in order to look out the door.
The problem is the magic bullet theorist don't take into account the actual jump seat location which makes the magic bullet in actuality act like a normal bullet.
I was convinced it was a conspiracy until I actually got into firearms and realized it wasnt a difficult shot. Also Natgeo reconstructed the shooting and replicated it almost exactly with the same rifle and ammo Oswald used.
Could there have been more people involved? Absolutely. Was the shot which hit JFK and Connally impossible? No, not when you take into account the actual seating locations.
