Prison/Jail - The ACLU of Utah filed a class action lawsuit on behalf of a group of prisoners at the Utah State Prison. The case involves an incident in August 2011 in which corrections officers released a tear gas canister in the Olympus wing of the Utah State Prison to subdue a single prisoner. The tear gas entered the air ventilation system and seeped into cells that have no windows or bars, affecting about 150 inmates. The inmates were left to breathe the noxious gas for about 20 minutes, and many feared for their lives. The Olympus wing is the mental health wing of the prison; it also houses prisoners with severe medical conditions.
