But keeping the cameras rolling is an important safeguard for society. Police have extraordinary power. Public scrutiny discourages abuse of that power. Videotape of the Rodney King beating in 1991 transformed Los Angeles policing.

That doesn't mean photographers have the right to get in the way, to trample over evidence or trespass on crime scenes or private property. They don't. Nor does it mean that photographers should shoot anything in sight. There are important questions of taste, ethics, news judgment and privacy that must be considered any time the lens is raised. But it is not up to police to make those judgments; it is up to photographers, editors and sometimes the courts.
