In what you just said it's always a possibility that, you know, it is conceivable. It is possible that the hand is in a certain position when something goes off. We know it is a graze wound, it didn't stay, so it had to go someplace. Could it have went into the door? Could it have reentered another area on his body? Could it have just went out into another place in space? All of those things are reasonable and I can't definitively say because I wasn't there to actually see the positioning of how the body was when it happened. It's possible, there is a multitude of ways that the bullet could have traveled after it struck the skin. Thank you.
