They Can Watch You, But You Can't Watch Them

The MTA is looking to ban photography and video filming in subways. While this may cut down on many bad pictures by art students, why does any authority have a right to limit photography in a civilian public place? More importantly, but simply using the subway system, riders are on video tape. No place or entity should have the right to limit a person's ability to take photography or film if in fact they themselves are under a security camera.
