Phoenix Sky Harbor Airport has been sued by the family of a woman who died while in police custody. http://www.cnn.com/2008/US/law/03/26/airport.death/index.html
Our take on this tragic story is that the police are not the primary ones to blame here. The woman was acting inappropriately, was detained, and in attempts to escape from detention she died. A tragic case, but not a negligent one.
