It is legal to photograph or videotape anything and anyone on any public property, within reasonable community standards.
Photographing or videotaping a tourist attraction, whether publicly or privately owned, is generally considered legal, unless explicitly prohibited by a specific law or statute. Neither members of the media nor the general public need permits to film or photograph in public places and police officers have no power to stop you filming or photographing incidents or police personnel. If your filming is questioned by a police officer, explain calmly and politely what you are doing.
