What are your rights as a photographer?

Dave Johnson, TechHive:

You probably don’t think about the legality of taking photos very much, but it’s more important than ever to be aware of your rights and responsibilities as a photographer—even if you aren’t shooting covers for Time magazine. It’s certainly true that the U.S. Constitution recognizes a formidable array of rights and freedoms; but when it comes to taking photos, in a lot of situations your rights aren’t so clear-cut.
