Greetings. I do some non-professional street photography in the U.S. and am concerned about the law. I'm shooting in a large urban setting, on public streets, people just being people. I can't seem to get a good definition of the law on this. While I'm walking/driving around capturing images, it wouldn't be practical to acquire a model release for each shot I fire off, and quite frankly, some or even many will not work, or be used. And these days, I doubt that many people would agree to sign. I've been asked to leave malls, and learned fast that the turf is off limits to photographers. It's funny...I was at one that caters to a rather affluent crowd, and didn't realize that I wasn't allowed to shoot. My auto-flash (digital) no doubt alerted the authorities and I was approached immediately. They were pleasant enough about it, but still insisted I stop. Many of the customers at this mall walk around with cell phones, cell phones with picture taking capabilities. How easy would it be to take a picture with a phone! But back to my question, I am strictly an amateur and just like shooting and sharing my photography. Does anybody have hard information on the legality?
