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

I am providing the link to Larry Rivera's study again because he has added some new material which pertains to the use of facial overlays in forensic science and the validity thereof. 

The fact is that this is a widely recognized and well respected technique to determine whether two images are that of the same individual.

It is state-of-the-art photo analysis, and it proves, with absolute certainty, that the Altgens Doorway Man was Lee Harvey Oswald.
