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

This is from the Lone Gunman people. They admit that it's Lovelady in the Couch film. 

It's nice to see that, but that's a very distorted image. We have better ones. The most important thing about the image is that Lovelady is wearing a short-sleeved shirt.

That was just seconds after the assassination- less than a minute. So, if that's Lovelady- and it was- then he could not possibly be Doorman, since Doorman is wearing a long-sleeved shirt. 

That wraps it up, don't you think?
