For some reason, security guards and cops have this weird aversion to photographers. Despite repeated statements from top brass in just about every jurisdiction, they insist that it’s illegal to take pictures of certain buildings or trees or power plants or whatever.
This must stem from action movies. In every movie with a terrorist, the guy goes and takes pictures of the target. This never happens in real life, of course, because we have things like Google Maps instead – but in movies, you need _something_ for the guy to do so you can pad the whole thing out to 100 minutes. So, pictures.
