So what? Been over 2,000 books on the JFKA. People don't write books on the JFKA to make money, if anything it's quite the opposite. LHO wasn't on the 6th floor when the motorcade went by the TSBD nor did he shoot JFK. There's no credible evidence that even shots were even fired from the alleged snipers nest.
1. Oswald had no verifiable alibi, so your conclusion is not supported by evidence.
2. The sizable bullet fragments recovered from the Limo and Parkland ALL came from Oswald's rifle which was recovered from the 6th floor!
3.
"Just after the President passed by, I heard a shot and several seconds later I heard two more shots. I knew that the shots had come from directly above me, and I could hear the expended cartridges fall to the floor. I also could here(sic) the bolt action of the rifle. I saw some dust fall from the ceiling of the fifth floor and I felt sure that whoever had fired the shots was directly above me."Harold Norman affidavit from the 4th day of December, 1963.

5. Oswald while in custody said numerous provable lies about the rifle and associated events concerning the rifle.
I could go on but it's getting late and I've had enough of the CT BS for one day.
