I often take the Greyhound bus to and from Cleveland, Ohio. It’s usually a quiet overnight ride, and now that many Greyhound buses have both power outlets and WiFi, it’s actually somewhat comfortable. On this particular trip back to New York, however, I was detained by police outside of the Greyhound station and told that it was “illegal to photograph Greyhound stations.” I didn’t really understand what law I was breaking, but I knew better than to press my luck and risk not actually being able to get home on time. Instead of telling me to stop (or even to simply leave the premises), the police officer took my camera and began to delete images off of the CompactFlash card. Ultimately, I knew that I had a handful of file recovery utilities at my disposal, but I’m pretty sure that if I wanted to file a lawsuit against the Cleveland police, I’d have a valid argument.
As you assumed at the time, there is no such law. If we give up our freedoms because of the threat of terrorism, then the terrorists have won.
