Oswald was arrested for the assassination of JFK and the death of Officer Tippit, but the document raises questions about his guilt. The document notes that Oswald had a troubled upbringing and schooling, and was not a particularly good shot during his time in the Marines. It questions why Oswald was allowed to return to the US from the USSR, where he had lived for a time, gotten married and had a child. The document's author personally believes Oswald did not do it, because the trajectory of the shot would have had to curve, which is impossible, and Oswald made comments praising Kennedy, so there was no clear motive.
