I work in a big office building located in downtown St. Louis, the "Bank of America Plaza." Early this week, I was interviewed for a newspaper article, and I needed an updated photo of myself. A coworker offered to snap that photo using a small digital camera. We want down the elevator to the first floor public lobby of the building, at street level, where we found a large neutral colored wall that we could use as a backdrop for my photo. I stood in front of the wall and my coworker stood about 10 feet away from me. As she took a photo of me a security guard suddenly approached. Me: "In the lobby? In a public lobby?" Guard: "You may not take any pictures here. It’s because of 9/11 and homeland security." Me: "I understand that your employers have instructed you to say these sorts of things, but what you have just told me is about the most idiotic thing I've ever heard. My coworker is simply trying to take a picture of me in front of a wall." Guard: "Sir you cannot continue doing this. You will need to take pictures elsewhere." We left. Apparently, taking pictures of me threatens the United States. Or maybe the threat was taking a picture of the wall behind me. Certainly, the guard made it clear that the building owners prohibit any sort of photos in the lobby. We walked across the street and threatened the United States by taking my photo inside the lobby of a office building across the street, where friendly security guards don’t appreciate the risk of what we were doing. Instead, they naively laughed at our stories about security guards in my own office building.
