What reasons did the HSCA have in 1979 for suggestions that President Kennedy was shot by lee Harvey Oswald acting alone?

It was obvious that Oswald was guilty. Among many other things, he was alone on the floor from which the shots were all fired. But there has never been any evidence, let alone proof, that he needed or had a co-conspirator.

Since the simplest explanation that fits the facts is the best one, the best explanation is that he acted alone Modern forensics have made it clear that all the shots came from his direction and weapon. The so-called "magic bullet", as we now know, went almost straight through both men, slowing up so much that it was not severely damaged aside from being squashed. The "Drain Man" sniper position would only have allowed shooting Kennedy's arm; while the Grassy Knoll position was blocked at the critical instant by a concrete wall.

The so-called "Badge Man", if there had actually been one, would have been the size of a cat.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
