There seems to be an interesting book out there I’d say on the basis of articles I have read called something like “Someone would have spoken” which deals exactly with that.
There was also Bugliosi’s recent book for the lone assassin theory, “Case Closed” I believe is the name of the book.
A lot of reading all around.
A good reference for those interested in the assassination is the JFK Lancer site. I don’t think it is political it just discusses theories. However, I’m dissapointed that it does seem they’ve added on some one with the oddball theories to their lineup or at least advertisers.
I still have some troubles about the some things, but most are caused by the FBI. Given what we know about the FBI's handling of high profile cases lately, that is no surprise.
