My guess would be, maybe it's something like NYC in that although it's a public space it requires a permit and they just don't issue any.
IIRC, An old Bruce Willis movie used a Metro station but it was empty, so if it was the real thing they had closed down the whole station for filming which Im sure added some annoyance.
