And also tangentially here How were members of the Stasi handled during German reunification? Was there a "de-stasification"?.
What happened to working-age Stasi employees after the fall of the Berlin Wall?.
A question of the history of the Stasi in general What are some good histories on the Stasi East German intelligence.
How were members of the Stasi handled during German reunification? Was there a "de-stasification"?.
