 So, John, thank you for having me on. First of all, I don't believe it was unguarded. There is no way that they missed that during the advance. There were assets, obviously, designed to neutralize any threats from that area. But we have to find out what went wrong. Why didn't they detect this individual? Why didn't the communication work between the witnesses to the police and forward to the Secret Service? That's something we have to look into.
