Prisoners ripped pieces of metal from lockers, destroyed beds and broke off pipes to use as weapons in a riot at the California Institution for Men in Chino on Saturday. A fire broke out during the chaos, burning down one dormitory. The disturbance was the prison's most violent since a December 2006 uprising in which 200 inmates rioted for 90 minutes. On Tuesday, officials allowed members of the media to tour the damage.
