You didn't miss much. Greta's show was much ado about woulda, shoulda, coulda with today's investigative standards which doesn't solve anything and isn't relevant. At the end of the hour I was still waiting for the earth shattering new evidence. The old PBS, "The Men Who Killed Kennedy" and last night's History Channel shows are much better. About the book, I wouldn't line the bird cage with it.
I'm going to have to watch that set of programs tonight on History at 8 ET, "The Men Who Killed Kennedy". Haven't seen this yet.
