Advice regarding the war against photography:
So what should you do if you’re taking photos and a security guard or police officer approaches you and tells you to stop? First, be polite. Security people have tough jobs and probably mean well. Ask them what legal authority they have to make you stop. (If you’re in a public place, like a street, a park, etc., they have none; if you’re in a private place, such as a shopping mall, they may have a basis for banning pictures.) Krages advises those hassled by security guards to threaten to call law enforcement. If it’s an actual police officer who’s telling you to stop shooting, ask to speak to a superior. And remember–you never have a legal duty to delete pictures you’ve taken.
I can understand our fear of another terrorist attack. But this article reminds me too much of what I witnessed living in the Soviet Union 23 years ago.
