Here’s something else that has always bothered me about the Oswald acting alone theory. He’s just assassinated the President of the United States and gotten out of the building and makes it all the way home to the boarding house he was living in. Why not just stay put? Why the need to go out and wander the streets and murder Tippitt? Why walk into a theater without paying? Why were numerous cops sent to arrest a guy for walking into a theater without paying in the middle of investigating the murder of the President and a fellow cop? Oswald could have sat in his room until the next morning and hopped on a bus anywhere.
The planners were more immediate-thinkers, choreographing the lead-up, the day-of, and the ensuing cover-up. They needed to make things seem kosher to the contemporary investigators of the time.
They were not thinking of all of us over the decades re-analyzing the events of that day. Actually, they couldn’t care less, since those that were behind it also controlled (and control it completely today) the media. Even publishers of history books.
