That was slick, linking LBJ with Hoover and localizing the assassination to LBJ and the FBI. He doesn't mention that Oswald appeared in the Christchurch, New Zealand newspaper in a stock photo in a suit just hours after he was assassionated. A photo not yet seen in U.S. papers. That could not in any way be done through LBJ and/or the FBI. Ugh...
LBJ's involvement has long been discussed and written about... it seems to me that St. John is the same guy I've always heard on shows (nothing against your interview Ed; it's just him).
