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

And by the way, if I get any actual challenges to the physics that this professor cited, if anybody tries to say that he was wrong about some specific thing because HE got the physics wrong, the science wrong, I'll show it to him, and then I'll let him explain to you why he's right, and you're wrong. 

He's a professor, and he's used to working with students who get things wrong, where further explanation and exposition are needed in order to turn on the light in their head. He knows how to teach; he knows how to illuminate. 

So, class is in session. If anyone wants to dispute anything specific he said, go right ahead.
