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

 This is me poised to shoot with my index finger on the trigger (left) and my middle finger (right). With my index finger, it feels like my hand fits the gun like a glove. It feels very snug and secure, with no play at all. Using my middle finger, I only have two fingers, my ring finger and pinkie, wrapped around the grip in front, which makes the grip a lot weaker.

But, there's something else that you can't see. When I use my index finger, it wraps the other side of the grip and holds it tightly. It's not just serving the purpose of pulling the trigger. It is gripping the right side of the gun. But, I don't get that effect when I use my middle finger. My index finger is just protruding forward into the cylinder zone, and my middle finger isn't gripping the gun either. I have nothing on that side of the gun that's really holding it tightly. There is no squeeze on it. I'll show you shortly.

The point is that Jack Ruby had an intact right hand, and both instinctively and deliberately, if he thought about it, he would have used his index finger on the trigger. Every small boy playing cops and robbers knows that the index finger is the trigger finger. You can't dream up a reason why Ruby would have done otherwise. And it's just another reason why that shooter in the Jackson photo cannot be Jack Ruby.
