Oswald had no library books at either of his residences (North Beckley or Irving) when he is alleged to have assassinated JFK. Considering he was such an avid reader, isn't this unusual and evidence he was perhaps planning something and so he knew he would not be able to return those books?
The only outstanding book he had was a book (The Shark And The Sardines) which he was supposed to have returned by Nov 13th but never did. Crucially, he had no book due on say Nov 23rd, Nov 24th, Nov 25th, Nov 26, Nov 27th etc.
Is this circumstantial evidence that Oswald perhaps afterall was up to something in mid to late November whereby he knew he would not be able to return any books should he take them out. Perhaps even planning to assassinate JFK?
