Today I noticed an Arabic looking man at the end of the parking lot taking pictures of the jets going over the building. I called the police, and within minutes they sent out three cars to investigate. It turns out that the picture taker works inside the building in a travel agency. There is uncontrolled access to the roof once you get past the outer entrance of the building.
The police didn't cut the guy loose outside the building, but ended up escorting him into the travel agency, and spending some time with him there.
A number of people at work have previously joked about a terrorist trying to shoot down jets from the roof of the building...
Wow.
