It's easy to show there was no conspiracy, as follows:
1. There is indisputable evidence that some bullets came from Oswald's rifle.
2. Therefore any conspiracy would have to have included Oswald and others.
3. No intelligent conspirators (CIA, Mafia, etc.) would have included Oswald because Oswald was a nut.
4. No provision was made for Oswald to escape. If captured, he would have spilled the beans.
5. No one would have relied on Ruby to "off" Oswald after capture. Too iffy. They would have "offed" Oswald shortly after the murder.
