 Where was the perimeter surveillance team? How did they miss this? Now, I told you in the opening of the show, I don't think you're hearing this anywhere else, I'm hearing from sources that a surveillance team, whether it was law enforcement or Secret Service specific surveillance assets, I'm not particularly sure. It's, at this point, not really relevant to the story. But someone detected this individual there very early and lost track of him. In other words, they knew there was a threat.
