Police, land owners, or other commercial and government officials may also demand you turn your camera off. Usually they will not have any legal authority to do so, especially if they are a government employee. Feel free to videotape police or other government people working in public areas, especially when it comes to their interaction with legal suspects. If you are on private property the rules are much different, but you cannot get in any more trouble for filming there than you can for just being there to begin with.
