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

"Detectives have their guns drawn." NBC reporter  Tom Petit

I have combed the films, and the only thing I have found is this guy putting his hand on what seems to be his pistol, but he doesn't draw it. He never takes it out. 

So, why did Tom Petit say that? In all the films, there is no evidence of any guns being drawn, except "Ruby's".
