Uniform), which focused on a lesbian relationship between a teacher and student. Both of these films received positive critical reviews and were commercial hits, opening in Berlin’s top theatres. Despite the positive reviews, there was still public outcry over Anders als die Andern including riots at the cinemas where it opened and it was even banned in various theatres including in Munich, Vienna, and Stuttgart. Berlin's reputation for decadence Prostitution rose in Berlin and elsewhere in the areas of Europe left ravaged by World War I. This means of survival for desperate women, and sometimes men, became normalized to a degree in the 1920s. During the war, venereal diseases such as syphilis and gonorrhea spread at a rate that warranted government attention. Soldiers at the front contracted these diseases from prostitutes, so the German army responded by granting approval to certain brothels that were inspected by their own medical doctors, and soldiers were rationed coupon books for sexual services at these establishments. Homosexual behaviour was also documented among soldiers at the front. Soldiers returning to Berlin at the end of the War had a different attitude towards their own sexual behaviour than they had a few years previously. Prostitution was frowned on by respectable Berliners, but it continued to the point of becoming entrenched in the city's underground economy and culture. First women with no other means of support turned to the trade, then youths of both genders. Crime in general developed in parallel with prostitution in the city, beginning as petty thefts and other crimes linked to the need to survive in the war's aftermath. Berlin eventually acquired a reputation as a hub of drug dealing (cocaine, heroin, tranquilizers) and the black market. The police identified 62 organized criminal gangs in Berlin, called Ringvereine. The German public also became fascinated with reports of homicides, especially "lust murders" or Lustmord. Publishers met this demand with inexpensive criminal novels called Krimi, which like the film noir of the era (such as the classic M), explored methods of scientific detection and psychosexual analysis. Apart from the new tolerance for behaviour that was technically still illegal, and viewed by a large part of society as immoral, there were other developments in Berlin culture that shocked many visitors to the city. Thrill-seekers came to the city in search of adventure, and booksellers sold many editions of guide books to Berlin's erotic night entertainment venues.
