Yet another show where the NSA shows up when anything paranormal occurs, like the NSA is some kind of all-knowing secret police. Folks... that's not what the NSA does. And even if it were true that the NSA were some kind of clandestine alien-seeking task force, they wouldn't announce it to the world every time they show up. Rather, they'd impersonate and introduce themselves as agents of the actual agency that would be investigating these things... the FBI (or, more likely, professional specialist contractors working at the request of the FBI).
