Officials in Florida say hundreds of prisoners took part in an uprising that saw damage to virtually every part of the Holmes Correctional Institution overnight Wednesday. The Miami Herald reports that 400 of the facility’s 1,100 prisoners took part in the uprising, stuffing blankets and sheets over windows and smashing surveillance cameras. Prison officials said riot squads and guards from five other prisons used canisters of gas to quell the uprising. Prisoners at Holmes say they’ve been confined to their dorms in recent weeks, denied recreation and allowed out only for meals, because the prison is woefully understaffed.
