Corbett is pretending to not notice the extensive evidence of a covert background for Oswald and accompanying pattern and interactions...Oswald was the only Marine who was allowed in to the Japanese district where CIA was spooking Russian contacts with Japanese prostitutes at expensive nightclubs...I believe what was really happening there was Oswald was offering to become a double agent in order to get bona fides before his "defection" to Russia...
Still waiting for someone to explain how Oswald knew about the obscure Swiss Albert Schweitzer College...
