Nice to see you admit that the rifle was crap. Doesn't it bother you that you have to rely on the "Well what do you expect he was a crazy man" excuse to attempt to rationalize LHO's actions? I do not think he was as crazy as he would have to be to fit this picture. He didn't sound crazy after the shooting. He didn't sound crazy on the radio in N.O. In fact, in both instances he sounded remarkably poised and well-spoken particularly for one with no education to speak of. His intelligence is verified by his ability to learn Russian on his own (apparently) so well that many believed him a native Russian.
It is not the case that my only problem with the WC is Oswald's motivations and actions there is the whole entirely separate problem of Ruby. And the Second Oswald sighting reported by numerous witnesses including the car salesman who took an "Oswald" for a test ride wherein HE drove.
Listen to what you're saying. Numerous witnesses saw him fire three shots from a rifle at the President. This alone proves that LHO was a hostile, irrational man. Rational, well-adjusted people do not fire guns at the President. From this unquestionable premise, you can then expect LHO to demonstrate a consistent pattern of irrational behavior and decisions. It's not an excuse or a rationalization. You must expect a pattern of irrational behavior from LHO based on the science of pyschology.
