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

 You should never EVER put your finger in front of the cylinder of a revolver because burning hot gases emit from the cylinder gap, as you can see on the right. On the left is Ruby's Colt Cobra 38 Special, the smallest snub-nosed 38 there is. If he used his middle finger, there would have been no place except along the cylinder for him to put his index finger.

But, Ruby didn't do that, and he wasn't even there. He was already tucked away on the 5th floor, and they had SS Agent Forest Sorrels minding him. But, FBI Agent James Bookhout, who masqueraded as Ruby, didn't do it either. I'm sure he used his index finger in the televised spectacle. But, he posed, for the world, using his middle finger, in the iconic photos that were taken at a photo-shoot an hour before the spectacle. We have testimony that they cleared the garage. to do it.
