 There is an outdoor rally with thousands of people and tens of thousands of people. Ask any police officer that's covered an event like this. There are suspicious people, and there are reports of suspicious people. And this creepy boy was crawling around the outer perimeter, not inside. You've seen the video of him looking away from the crowd and walking along the side of a building and stuff before he got to the building where he went on the roof. And he was reported as a suspicious individual.
