 What the hell happened? Who didn't do their job? I mean, how in the world are people talking about how did a guy walk across an open area with a long gun, crawl up the side of an empty building? How did he know that building wasn't, in fact, you know, being, you know, looked at by the police, by the Secret Service? How do you know it was safe to go up the side of that building? How do you know it was OK to lay on top of that building?
