I suppose I can understand the thinking. Taking pictures can be part of an intelligence gathering operation for any prospective terrorist.
Unfortunately, taking pictures of subway platforms and trains is also a big part of a tourist's NYC experience. Every visitor, it seems, wants to be photographed in a setting made familiar by thousands of movies and television shows. It would be a real shame to stop that.
I think the MTA is mistaken for a couple of reasons:
- any terrorist can discreetly use the latest in miniaturized photography equipment to get what he wants without risk of detection;
- there is probably more chance of thwarting a terrorist attack by encouraging people to take pictures on the subways what terrorist will not think twice if he's just found his face accidentally included in a family picture taken on a subway platform;
