How Nazi secret police files could stop terror attacks

The Nazi secret police were among the first to use geoprofiling to locate resistance fighters based on leaflets they distributed. Now scientists believe similar methods could track terror cells.

Nazi secret police files detailing the hunt for resistance fighters in Berlin during World War 2 could be used to locate terrorist cells today, scientists believe.

The Gestapo was one of the first organisations in the world to use the technique of geoprofiling in the search for husband and wife Otto and Elise Hampel.

After learning of the death of Elise’s brother in France, the couple began distributing postcards with anti-Nazi messages in apartment buildings around Berlin, hoping to encourage resistance.
