Crime in Adelaide: Crime in the city of Adelaide, South Australia has decreased significantly since the 2000s and is controlled by the South Australia Police (SAPOL) and the South Australia court system.  Adelaide has developed a reluctant reputation over the years as Australia's "crime capital", despite it being a relatively small city.  Perhaps one of Australia's most notorious and well known serial killing cases, the Snowtown murders, occurred primarily on the outskirts of Adelaide in the low socio-economic areas of Salisbury and Elizabeth.  This, as well as a series of unsolved murder cases in the 1970s, 1980s and early 1990s, known as "The Family Murders" led to one UK documentary dubbing Adelaide the "murder capital of Australia".  Various highly publicised kidnappings have occurred in the city, notably the unsolved Beaumont children disappearance on Australia Day in 1966.
