I fully appreciate them covering their rears, and I'm not a stranger to being asked to not take pictures.  Wandering around and taking pictures of things for Commons, I've gotten talked to by more than a few security guards in my time (up to several times a day).  But every time up until now has been a pleasant encounter.  The Station Agent skipped the step where they inform me of their "No Photography" policies, and ask me politely to stop - and I always do.  The agent today skipped directly to the "I'm going to call the cops" step, as if what I was doing was illegal in the first place - which it ISN'T.  They can ask me to stop, and to leave - they can't call the cops.

What is right and wrong isn't the point though.  The attendant did what they thought was right (I guess).  I just wanted to warn everyone else so no one actually ends up in jail because they were out taking pictures for Wikipedia/Commons.
