Not sure what that means

There are some crackpot theories running around including one that the Oswald who killed JFK was a subsitute from the one born who enlisted in the marines.

A good book to read is Anthony Summers' Not in Your Lifetime gives good evidence of conspriracy and some interesting facts about Oswald and Ruby.

I've also read Gerald Posners book Case Closed and it gives evidence of Oswald being the lone gunman.

A good book on Ruby is The Ruby Coverup by Seth Cantor
