> you know he's a terrorist because he is pointing a telephoto lens at an airplane I picked up my brother at SFO a few years ago, and walked around outside the airport terminal building to get a good view of the runway and take a picture of the Lufthansa A380 my brother was landing in, when an SUV pulled up with security and asked me what I was doing and told me to go away.
