 So what did go wrong with security? How was a gunman able to get so close? And who was the would-be assassin? We'll hear from his former schoolmates. He was overall a nice kid. He was quiet. He was always alone. I mean, he was bullied every day. All that plus the photographer who captured an image of the bullet mid-flight. She goes, we think there's a bullet flying behind his head in one of the pictures. And I got chills and I was like, oh my God, are you kidding me?
