I am retired military and all of my kids and wife have a brown ID card. I know what one looks like and the photo in the book is definately a clear legible photo of a brown military ID. Not a card that is defaced or damaged and "could" be a brown ID. Also, as a former US Navy admin officer, the ID card rules you mention do not exist. The CIA are not military so they are not issued any type of military ID card. In the 70's and 80's, CIA personnel were escorted everywhere on USAF and USN bases. So were they to be 'there' long enough and have a need to shop, their escort would naturally have taken them. Just like the foreign officers/personnel stationed on an American base. None of the Japanese officers on our American base were given American ID's to shop. None of the books I've read (including all of Gerald Posner's) make any statement about Oswald being a suspect in JFK's death PRIOR to his arrest. Oswald's arrest has been suspicious from the outset. Dallas PD was not as big then as it is now. They are looking for the president's killer and yet they have 20 cars to spare for a '911 call' saying "there's someone in my movie theatre creating a disturbance?" Notice at no time did the caller say "I have a guy in here claiming he shot the president." And if he was a suspect and they knew he was in the theatre (remember, no GPS, enhanced 911 or cell phones in 1963) then why only 20 cop cars? And why not call the other cars in that were busily combing Dallas for JFK's shooter?
