Damien

It seems kind of a pointless discussion. I think the FBI director was guilty of caring too much about the precise details in a format where any nuance would be lost. To him, it is a difference if it was a bullet or debris from the bullet as it broke up (?) in midair but that has allowed some people to spin at as if he wasn't hit at all.

I think it probably was debris since his ear healed pretty quickly, he clearly hasn't had a chunk taken out of it, so as we know it was quite lucky he moved his head.
