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

This collage shows very well the discrepancy of the chin in the Backyard photos. That anvil-like chin was not Oswald's.

Now, that had to be done BEFORE the assassination, and if they were altering photos BEFORE the assassination, don't you think they were prepared to alter photos immediately AFTER the assassination, such as the Altgens photo? You bet they were.
