Is there a qualified immunity defense in the context of allegations that prison officials condoned brutal reprisals against inmates?

Hendricks v. Coughlin, 942 F.2d 109, 113 (2d Cir.1991); see also Al-Jundi v. Mancusi, 926 F.2d 235, 240 (2d Cir.1991) (denying qualified immunity defense where prisoners alleged that prison officials, in violation of the Eighth Amendment, condoned brutal reprisals against them after prison was retaken from rioting inmates).
