The shot that killed Kennedy came from above and beind and there is no evidence to the contrary
You're right about that. There was no shooter from the front. Its easy to dismiss the claims otherwise. Two shooters? Kennedy was hit twice by 2 shooters? They were not very good snipers if that were the case.
What isn't so easily dismissed is Oswald acting alone. The actions before and after the killing were really peculiar. For one thing, why not bring your pistol with you if you're going to shoot the President with a rifle? Surely anyone would expect some sort of post-assassination confrontation. Going home to get your gun when you could have brought it with you makes little sense UNLESS you don't foresee needing it. Now why would he not need it? If you were promised some sort of "get away" or someone else to take care of the opposition in the post-assassination confrontation....I can see leaving the gun at the house. Outside of that...no reason to not come heavy.
Then...winding up at a movie theater. Again, sounds strange unless you're going to meet someone in a place where you can't be seen very easily.
I've posted my theory here before (no proof of this of course) but here it is again.
=====
Fact. In the month or so before 11/22/63, Oswald went to Mexico City and visited some Eastern Bloc embassies trying to re-defect to Cuba or the USSR. He was turned down.
My theory (this is what I'm looking for from you in regards to 9/11) is that he told someone at the Cuban embassy that he would kill Kennedy. He likely tried to "trade" on his previous attempt in the Spring on General Edwin Walker but Cubans were not impressed. Walker (like most generals) was a devout anti-Communist. So Oswald offered up Kennedy. My theory continues that the Cuban embassy officials in Mexico City didn't contact Havana and likely not the Mexico City station chief. I think one of the staffers there told Oswald, basically to "knock himself out" when it came to killing Kennedy--not thinking that this guy would go through with it. But if he did...all the better. My theory continues that at some point, in Dallas, the unofficial Cubans at the embassy in Mexico City through intermediaries got to Oswald and told him that they would ferry him out of the country after he killed Kennedy.
Fact. Oswald left his rifle in the Texas School book Depository (TSBD). He was seen carrying a large package into the TSBD.
Fact. Oswald left his wedding ring and $170 for his wife before leaving.
Fact. Oswald had a revolver that he didn't bring with him although he could have very easily have brought it with him.
My theory continues that after he killed Kennedy he left the TSBD and expected to be picked up by his unofficial Cuban contact. This was, of course, never going to happen since it was never an official operation by Cuban Intelligence. It was a guy in the Cuban Embassy in Mexico who was free-lancing. So when he knew he'd been had...he starts taking evasive action...taxis, a bus, and ultimately showing up at the Texas Theater--likely where he met the intermediary.
Fact. When arrested, Oswald said "I'm just a patsy" He didn't say he didn't do it--admittedly he didn't have a lot of time with the press. But it seems to me that he'd say "I didn't do it!" I mean...if you were to be accused of something this serious...I would be shouting "I didn't do it."...not "I'm just a patsy".
Conclusion:
If he left behind his rifle and didn't bring his gun, one can logically surmise that he didn't think he'd need them. He thought he'd be on a flight to Havana or Mexico.
Since he left his wedding ring behind and his life savings, one can logically surmise that he didn't think he'd be needing them or predicting he wouldn't return. So again...if he didn't think he'd have the help I speculated about before...why not bring the revolver with you?
