The bullet points seem to be mostly confusion at the scene and shitty police work afterwards.
What is the conspiracy. That he was not killed at that spot, but later by the secret service? Like "that guy fired blanks at him, lets kill the PM and frame him"?
I never really understood the logic because it is deeply oxymoronic. People that generally wanted him dead (ultra right) think that he was killed by the secret service (presumably left) and Yigal Amir (ultra right) was framed.
But it is something about putting blank bullets in order to gather support with a fake assassination and then he was really killed by the Shabak on order of Shimon Peres (but can’t say that’s verbatim)
It always seemed even less internally consistent than most JFK theories
