Developments in technology have raised questions concerning law enforcement authority to stop members of the public, including suspects and witnesses, from recording or taking photographs of officers or others in public spaces or public view.
Citizens have a right to record matters of public interest, including a right to record police activity under the First Amendment. However, individuals may be lawfully required to move out of the way of police activity so as not to obstruct it or endanger themselves or others. As such, it is to your advantage to keep a safe distance from police activity should you wish to observe or record police activity.
