Your photography rights

If you can see it, you can shoot it
Let's get the easy stuff out of the way. Aside from sensitive government buildings (e.g., military bases), if you're on public property you can photograph anything you like, including private property. There are some limits — using a zoom lens to shoot someone who has a reasonable expectation of privacy isn't covered — but no one can come charging out of a business and tell you not to take photos of the building, period.

Further, they cannot demand your camera or your digital media or film. Well, they can demand it, but you are under no obligation to give it to them. In fact, only an officer of the law or court can take it from you, and then only with a court order. And if they try or threaten you? They can be charged with theft or coercion, and you may even have civil recourse. Cool. (For details, see "The Photographer's Right.")
