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

So, here's Bogart questioning three men about who shot the priest, but they won't say. So, he starts with the rifle of the man on our right.

Then, he proceeds with the rifle of the man on our left.

And then he proceeds to the rifle of the man in the middle.

And he knows right away that he's the one who shot the priest.

So, why didn't they do the similarly with the 6th floor rifle and with Oswald's revolver from the theater? How come we have heard nothing about anyone sniffing the muzzles of these weapons?
