looks like to anyone else is nitpicking and obsessing over irrelevant details.
Whether we like it or not, all that matters now is the picture, and it was a picture of a real event, a real assassination attempt, against a real candidate by someone with a real gun with real bullets. Denying it is just energy wasted. And frankly, the less we talk about it, the faster it goes away.
