High, mentally ill man shouts at Newport Beach, Calif. police from within a convenience store, pantomimes having a gun, tells police to shoot him. Police take position outside, behind car doors. He runs toward them brandishing what turns out to be a metal display hook. They shoot, kill him. Excessive force? Quite possibly, says a Ninth Circuit panel. But that wasn’t clearly established, so the man’s parents can’t sue under the Fourth Amendment. Their state-law claims should not have been dismissed, however.
