On January 1st, 2015, Norway's national archives opened up long-sealed court files dealing with tens of thousands of Norwegians accused of treason during World War II. Any Norwegian can now find out whether their family members, some of whom may be still alive, collaborated with the Nazi occupiers.
Within a few weeks, thousands of Norwegians applied to see the files. After 70 years, many are now being confronted with their Nazi past. For some families, the revelations are a shock. For the first time, the country is openly debating the full extent of the "betrayal" during the German occupation.
