Examining One of Trump’s “Assassination Attempts”

It’s weird that no one talks about this anymore (did we talk about it at all?), but how likely is it that the assassination attempt against Donald Trump in which he was supposedly hit in the ear by a round from an AR-15 didn’t leave a scar?  Not even a scratch?

Why can’t some teenage cub reporter follow this down and show that the likelihood of this actually happening is like rolling a six on a die 1000 times in a row?
