By the way, be very careful if you try shooting such scenes - the security guards will fall over you like a ton of bricks if you are spotted. A situation for which small unobtrusive (and automatic functioning) cameras are advantageous. I took my chance with my Nikon D3 and the 35/1.4 AIS and got away with it.
