McKnight v. Peterson

(1) Whether, viewing the facts from the petitioner's perspective, he acted reasonably, under the Fourth Amendment, in firing in self defense, when an officer in his situation would believe that the suspect was armed, was suspected of a violent crime, refused to show his concealed hand, refused commands, and came at the officer; and (2) whether the petitioner was entitled to qualified immunity, when existing precedent did not clearly establish that the use of deadly force was unlawful under the particular situation faced by the officer, and the U.S. Court of Appeals for the 9th Circuit's analysis contravened the U.S. Supreme Court's explicit directions.
