Cameras to be Forbidden in the NYC Subways?

One of the most common photographs taken by tourists while in New York City is not the Statue of Liberty or the Empire State Building, but rather of the family braving that most-feared-and-most-beloved mathod of transportation: the subway. ("See, ma! I really did sit next to come guy with a clothespin through his nose!") Well, now according to Photo.Net there is a proposal underway to ban all amatuer photography from ths subways (and busses). While this is being done under the aegis of antiterrorism, the author rightly notes that this only has the virtue of stopping photographers using things that look like cameras. Camera-phones, mini-digicams, and those cameras easily hidden in common objects are not likely to be noticed by any enforcement authority. Thus, all cameras are banned... except for the kind that a terrorist is most likely to actually use to avoid drawing attention to his/herself. Does this really make sense?
