Your neighbor annoys you? They aren't patriotic or christian enough? They are kind of weird and keep to themselves?
Just report them to the Gestapo/Stasi and they will mysteriously disappear, never to be heard from again:
Its been estimated that only 15 per cent of Gestapo cases started because of surveillance operations. A far greater number began following a tip-off from a member of the public. Every allegation, no matter how trivial, was investigated with meticulous and time-consuming thoroughness. Its been estimated that about 40 per cent of these denunciations were personally motivated. A Berlin stoker reported a prostitute who gave him venereal disease. She was placed in a concentration camp. Gestapo officers were extremely wary of husbands and wives who informed on each other. A housewife in Mannheim told the Gestapo her husband was making derogatory comments about Hitlers regime. After a lengthy investigation, it emerged that the wife wanted her husband out of the way to continue a love affair with an off-duty soldier. In another case, two married doctors were involved. The wife accused the husband of carrying out illegal abortions. This led to his arrest and imprisonment. The husband claimed his wife had a vengeful motive. The husband had passed on a sexually transmitted disease to his wife, while carrying on a love affair. Her motive was revenge, but he served eight months in prison before this was finally established.
