McCoy v. Alamu

(1) Whether a prison official is entitled to qualified immunity if he gratuitously assaults a prisoner but not every factor from Hudson v. McMillian for when the use of excessive physical force may constitute cruel and unusual punishment favors the plaintiff, as the U.S. Court of Appeals for the 5th Circuit held here, or whether the plaintiff can nonetheless defeat qualified immunity, as the U.S. Courts of Appeals for the 4th, 6th, 9th and 11th Circuits have held; and (2) whether a prison official who assaults a prisoner without justification is entitled to qualified immunity if past precedent involved different mechanisms of force, as the 5th Circuit implicitly held here, or whether precedent concerning unprovoked assaults by one weapon can clearly establish the unconstitutionality of unprovoked assaults by other weapons, as the 4th and 9th Circuits have held.
