Oswald's movements and actions--after the assassination shots were fired from the TSBD--are evidence.
Explain why this piece of evidence is not, in your opinion, evidence:
-- Lee Harvey Oswald attempted to shoot officer Nick McDonald with his (Oswald's) revolver when about to be arrested.
Because claims aren’t evidence. The
claim that Oswald attempted to shoot McDonald is nothing but an assumption based on some people hearing a click in the theater during a struggle in which many hands were on a gun. I don’t know how you determine intent from that.
But let’s say that it was irrefutable that Oswald tried to shoot McDonald. That would tell you exactly nothing about who killed Kennedy.
