I've never accepted the Warren Commission's conclusion that Lee Harvey Oswald acted alone. Movies like "JFK" did a lot to fan the flames of popular mistrust. With so many inconsistencies in the story, I suspected there had to be more to it than what we've been told. That was until yesterday. I happened to catch the episode of "Unsolved History" reconstructing events of that fateful day in Dallas. One by one, they convincingly addressed each conspiracy angle and proved that Oswald DID act alone. For example, they claimed Oswald couldn't have fired 3 "hits" in 6 seconds. They recreated the scene exactly and found that a marksman - which Oswald was, could easily do it. In fact, the last shot was the easiest. Another issue: Oswald's movements immediately afterwards. Conspiracy theorists have long maintained that Oswald couldn't have gone from the 6th floor sniper's nest to the 2nd floor lunchroom in 90 seconds. And if he did, he'd be out of breath - which Oswald wasn't. To test this theory, they selected someone in the same shape and size of Oswald to retrace the steps. Well, the double did it in well under 90 seconds - without even being slightly winded. Finally, they got to the murder of Officer J.D. Tippet at 1:15. Oswald's landlady saw him leave the boarding house at exactly 1pm. At 1:15, Tippet stopped a man "walking briskly" a mile away. Could he have walked one mile in 15 minutes? Again, they used the double to time his progress along several different routes based on conflicting eye-witnesses. The most credible witness saw Oswald walking along a route that took the double only 11 minutes to reach the spot of the Tippet murder. So, after decades of suspicion, I'm now totally convinced that Lee Harvey Oswald acted alone.
