It was a failed assassination attempt and the appropriate people are being held accountable for it. I'm not sure why we are still talking about this beyond a footnote in history. Honestly, I don't really care if he was grazed by a bullet, he was hit by shrapnel, or a secret service agent squirted him with fake blood when he was on the ground, there just isn't much more to talk about. Well, ok, if the Secret Service actively participated in a stunt to fake an assassination attempt there would be a lot more to talk about. I just don't think that's what happened and haven't seen any compelling reason to think it did. Incompetence does not equal participation in a conspiracy.
