Anyway, to get back to the original question of this thread; why did Saint Patsy go to the movies ?
I submit that the evidence clearly shows that Saint Oz was in flight. He didn't plan to go to the movies. He just happened to wind up in the theater after murdering Ofiicer Tippit.
There is an extremely remote possibility that the theater was a pre-arranged place to meet at after the assassination, but there's not a shred of evidence to support that idea, and plenty of reasons to doubt it.
I find it interesting that none of the conspiracy clowns have stated why they think Saint Patsy went to the movies.
