I posted this a couple of years back (under a different avatar). Got a couple of interesting comments but nothing definitive
Now you can buy cards that tell you what you can or cant do.
- in the US no-one has the legal right to ask you to delete a photo from your camera (not even the police)
- new laws in some states prohibit taking photos of law officers !!
- shopping centres are deemed public places and security guards have no rights to stop you taking photos
As photographers we should know our rights - not have to have arguments with security guards in shopping malls !!
