 CBS's Jim Cressula reports on a haunting find in Europe. Renovators at Poland's Auschwitz-Birkenau State Museum have uncovered 35 well-preserved handmade chess pieces. They were set in the prison's first floor to avoid detection from the brutal Nazi guards who patrolled the cells. Given that Auschwitz guards would routinely beat, torture, and execute prisoners for trivial matters, it stands to reason that any prisoner caught with the chess pieces would face horrific consequences.
