Saw one last week about the JFK assasination, not sure when it was first aired, where they debunked the usual theories. In this one, they also worked out where the missing bullet went from the first shot. It also explained the locations of the shell casings on the floor where Oswald shot him from. They found Oswald took his first shot just after the car turned left into Deley Plaza- eye witnesses at the time spoke of hearing a shot at this time - but couldn't figure out how he had missed. From looking back at the re-creation the Secret Service did at the time, they realised the shot had hit the traffic light as the car passed under it, fragmenting the bullet.
The casings on the floor, two can be seen to be clearly together, this is the second and third shot and one on its own
Grainy pictures, but daylight can be seen through the hole in the bottom left.
