Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

This is an interview of John Armstrong, and he starts off by making a valid point, that a simple DNA test could settle this whole issue right now, and once and for all. And that DNA test would be between Robert Oswald and either or both of the daughters of Lee Harvey Oswald. Even an uncle/niece connection would register on the DNA test. But, that has not been done, and no doubt Robert Oswald would never agree to do it precisely because he is not related to June and Rachel.
