The entire narrative of Oswald as soon as he left the Depository immediately after the assassination is only indicative of guilt. But the Texas Theater is perhaps the most damning because the evidence cannot be disputed and hence the absurd attempts at refutation.
Oswald was observed avoiding cops.
No, Oswald was observed looking in a window. Everything else was conjecture.
Oswald snuck into the Theater.
Nobody observed Oswald sneaking in to any theater.
Oswald punched a police officer.
Possibly he took a swing in self-defence. But it's disputed who threw the first punch.
Oswald was carrying a revolver.
Also disputed. Only Nick "captor of Oswald" "serial teller of falsehoods" McDonald ever claimed to see a revolver on Oswald at the theater.
Oswald tried to use the revolver.
Also conjecture. There was a click or a snapping noise at a time when several hands were on the gun and it was pointed at a 45 degree angle toward the screen.
But exactly none of these claims, even if they happen to be true (and you haven't demonstrated them to be anything but empty claims), tell you anything about who killed Kennedy or Tippit.
