I shouldn't have said it so definitively, but I was listening to reports by the major media. I would think that if a bullet even grazed his ear it would have taken a chunk out of it. Either way it's an unfortunate incident but doesn't make Trump any less of a sociopath wannabe dictator with plan to enact vengeance on people he perceives are his enemy. Or a pathological liar or convicted rapist, pedophile, pathological liar, etc.
I find that it's difficult to get real news these days. Journalism is mainly dead. I think one of the major broadcast media also mentioned the glass theory as well. I'd have to hunt for it.
To be fair, though, Snopes says it was a bullet:
"Because there is photographic evidence of a bullet striking Trump, and of the wound created by that bullet, early and imprecisely sourced claims that Trump's injuries stemmed from broken glass are False."
