Putting up a dummy camera sure seems like one action taken to make people feel safer to me. It isn't the whole theater, just part of it. Public transportation of the terrestrial variety has very little theater, and very little security anyway. Even the cameras that do work probably exist for the playback, not for the live "surveillance". I just don't think they're watching closely enough.
