Denmark authorities lying about attempted murder.

Full-time officers were posted to all major industrial plants (the extent of any surveillance largely depended on how valuable a product was to the economy)[19] and one tenant in every apartment building was designated as a watchdog reporting to an area representative of the Volkspolizei (Vopo). Spies reported every relative or friend who stayed the night at another’s apartment. Tiny holes were drilled in apartment and hotel room walls through which Stasi agents filmed citizens with special video cameras. Schools, universities, and hospitals were extensively infiltrated,[24] as were organizations, such as computer clubs where teenagers exchanged Western video games.[25] The Stasi had formal categorizations of each type of informant, and had official guidelines on how to extract information from, and control, those with whom they came into contact.[26] The roles of informants ranged from those already in some way involved in state security (such as the police and the armed services) to those in the dissident movements (such as in the arts and the Protestant Church).[27] Information gathered about the latter groups was frequently used to divide or discredit members.[28] Informants were made to feel important, given material or social incentives, and were imbued with a sense of adventure, and only around 7.7%, according to official figures, were coerced into cooperating. A significant proportion of those informing were members of the SED. Use of some form of blackmail was not uncommon.[27] A large number of Stasi informants were tram conductors, janitors, doctors, nurses and teachers. Mielke believed that the best informants were those whose jobs entailed frequent contact with the public.[29] The Stasi’s ranks swelled considerably after Eastern Bloc countries signed the 1975 Helsinki accords, which GDR leader Erich Honecker viewed as a grave threat to his regime because they contained language binding signatories to respect “human and basic rights, including freedom of thought, conscience, religion, and conviction“.[30] The number of IMs peaked at around 180,000 in that year, having slowly risen from 20,000 to 30,000 in the early 1950s, and reaching 100,000 for the first time in 1968, in response to Ostpolitik and protests worldwide.[31] The Stasi also acted as a proxy for KGB to conduct activities in other Eastern Bloc countries, such as Poland, where the Soviets were despised.[32] The Stasi infiltrated almost every aspect of GDR life. In the mid-1980s, a network of IMs began growing in both German states. By the time that East Germany collapsed in 1989, the Stasi employed 91,015 employees and 173,081 informants.[33] About one out of every 63 East Germans collaborated with the Stasi. By at least one estimate, the Stasi maintained greater surveillance over its own people than any secret police force in history.[34] The Stasi employed one secret policeman for every 166 East Germans. By comparison, the Gestapo deployed one secret policeman per 2,000 people. As ubiquitous as this was, the ratios swelled when informers were factored in: counting part-time informers, the Stasi had one agent per 6.5 people. This comparison led Nazi hunter Simon Wiesenthal to call the Stasi even more oppressive than the Gestapo.[35] Stasi agents infiltrated and undermined West Germany’s government and spy agencies.[citation needed] In some cases, spouses even spied on each other. A high-profile example of this was peace activist Vera Lengsfeld, whose husband, Knud Wollenberger, was a Stasi informant.[29] Zersetzung (Decomposition) Main article: Zersetzung The Stasi perfected the technique of psychological harassment of perceived enemies known as Zersetzung (pronounced [ʦɛɐ̯ˈzɛtsʊŋ]) – a term borrowed from chemistry which literally means “decomposition“.
