If that's what actually happened
There's no evidence of this whatsoever.
"tries to shoot a police office that asks him to stand up inside the movie theater."There's no evidence of this whatsoever.Some folks believe that it was Lee Oswald who shot JD Tippit ( even though Mrs Roberts said that Lee was standing outside the rooming house just two minutes before Mrs Markham saw JD Tippit shot by the killer)...... And they believe that Lee was in a panic and responded by shooting Tippit in the blink of an eye, but he wasn't in a panic at all just minutes later when Officer Nick Mc Donald approached him in the theater..... Think about this improbability.....If Lee had been so irrational to shoot Tippit, he would have been even more panicky when Mc Donald approached and would have known that he was headed for the electric chair after shooting Tippit , he therefore would have known that he had nothing to lose if he could shoot McDonald and escape the theater.... The fact is...Lee showed no sign of being a cornered rat, who was ready to go down fighting.....
