I think it’s worthy of an article because I remember hearing initially, right after the shooting, that it wasn’t quite known if he was actually hit by a bullet or shrapnel. This tells me this is still the case and there hasn’t been a definitive answer given.

I wonder if the doctors who treated him know? Is it possible to determine based on the injury if it was a bullet vs shrapnel?

It looks kind of dumb though if I’m being honest. You can easily tell if someone didn’t inhale and instead just kept it in their mouth. Doesn’t look as complete. For acting, I’d consider this an issue.
