Libberding reports a photography class she teaches went into the bowels of Harvard station tonight to, well, take photos. And they were promptly blocked by T workers who told them to knock it off, even though official T policy specifically allows non-commercial photography on T property (with certain safety caveats, such as no use of flash):

As we were talking, another MBTA employee caught another one of our group taking photos, and pulled him towards us. Eventually, I got around to showing each employee (by now, there were three of them gathering us together) what their own website said.
