BERLIN, GERMANY - SEPTEMBER 17: A view of hundreds of files lining the shelves in the archives of the former East German secret police, known as the Stasi on September 17, 2014 in Berlin, Germany. The Stasi, whose official function was to protect the East German communist party, pursued an extremely aggressive campaign of spying on East German citizens in order to confine and root out dissent. The archive contains information gathered by the Stasi on millions of people. This November Germany will commemorate the 25th anniversary of the fall of the Berlin Wall which led to the demise of communist East Germany. (Photo by Carsten Koall/Getty Images)
