First my newly puchased $10 Metro Card would not work and kept indicating "swipe again', endlessly. That should have been an omen. I took out a camera from a bag and went to photograph a stopped S shuttle train. Two oficers immediately accosted me with "photography of subway trains is forbidden" and threatened me with a summons. I knew they were mistaken but did not have a copy of section 1050.9 on me so I merely suggested that they were mistaken. No sir, you can only take pictures at the transit museum. Ok, officers and I identified myself and put the camera away so no summons, but jeez how hard is it for Police Officers to know the laws and regulations that they are to enforce? Can't the NYPD just tell oficers of the MTA regulations? I know of the heightened alert right now and if the officers had just said something like " Sir, because of the heightened alert right now we would appreciate it if you were to forego your photography for a week or so or, perhaps, go to a less conspicupus spot than Times Square" I would have been apologetic for creating a stir but when they announce themselves with "photography of subway trains is forbidden" my response is bound to be an unhappy one. I once had a position of authority where I had to enforce rules and regulations. I had to know them and if i tried to incorrectly enforce some regulation I would have been in big trouble. I sent a complaint to the NYPD, quoting the MTA regulation on photography and explaining my experience. I'll let you know if there is a response. PS I also wrote to the MTA for my money back on the Metro Card
