Eighth Circuit
Brown v. Fortner, 518 F.3d 552, 561 (8th Cir. 2008) (“We conclude that Fortner had ‘fair warning’ that driving recklessly while transporting a shackled inmate who had been denied the use of a seatbelt and ignoring requests to slow down violated the constitutional prohibition against cruel and unusual punishment. There is no question that it was clearly established that subjecting inmates to unreasonable and substantial risk of harm constituted a constitutional violation.”).
