We've kind of hit on it, but reading twitter and FR, the part about this that really disturbs me is the lack of discernment and willingness to jump on the train by so many people. I see this story being fabricated out of thin air and passed around like the Chinese story game.
Someone on FR just wrote an entire narrative about this....
The people in the rally said he had a gun. They said he had it in a holster and the people around him spotted it and held his arm down where he couldn’t fire it until the Secret Service got there.
...and now everyone is passing that story around like it is the truth. Who knows how the story will change in five minutes.
