the findings of the Warren Commission in the main.
The ONLY thing they disputed was the idea that Oswald was the lone gunman. They were ready to agree with that as well, until 11th-hour testimony was presented by two scientists who asserted that a dictabelt recording made from a police motorcycle implied there were four shots fired, not three. That "evidence" has since been conclusively refuted by proof that said motorcycle was not in a position to record what they said it recorded. That evidence is clear through photographic and video evidence that clearly shows that the motor cycle was 170 yards away from the intersection of Houston and Elm where those two scientists said it had to be to make the recording. The pictures and videos don't lie.
Case closed, as Posner said.
BTW - what "high quality research" are you referring to?
