 The shooter was taken down by Secret Service agents. One person in the crowd was killed. We are now learning there are two patients at Allegheny General Hospital who were injured. Both are in critical condition. Madison Brooks from Uniontown, Pennsylvania, witnessed the shooting. We, like, watched him go down and hit the ground, and everybody was screaming, like, get down, get down. And then the next thing you know, the Secret Service is barricading him, and he's throwing his fist up in the air. But it was so scary because we were, like, five feet away from the guy.
