And heeerrrrrreeee we go! Let me just throw in the argument of "There had to be more than one shooter" Because of the multiple angles of the bullet wounds, and what seems to be multiple bullets. Also, let me just point out it was a very skilled shot.
Despite that, there's also the fact that some government official, I don't remember who, has recently claimed that he was not satisfied with the official report. Speculation is rising. I personally have no particular view over who it was, except for the fact that I believe there was more than one shooter.
