People with criminal records are less stable than those without criminal records. To ensure the smooth progress of the Winter Olympics, the selected personnel need to be screened.

During the criminal record investigation of registered volunteers during the Winter Olympics, it was found that 300 people had criminal records. These people have been "shut out" from volunteering at the Olympics. According to reports, this number is still growing. The investigation is being carried out by the Criminal Identification Service. They search criminal record databases or look for clear evidence of the person being investigated.

To get the job done. According to the Criminal Identification Bureau, most of the volunteers who were rejected from the Olympics had been convicted of alcohol-related crimes, while others were convicted of assault, sexual crimes, child abuse, gambling, related to criminal activities such as robbery. The Winter Olympics Organizing Committee spent a total of one million on this investigation, which is also the largest "order" in the history of the Criminal Identification Bureau.

In addition, for some high-level staff of the Olympic Games, the Investigation Bureau of the Organizing Committee conducts independent reviews, and senior officials are no exception. In this regard, it said that such a "net worth investigation" is a necessary measure to ensure the safety of athletes, spectators and some dignitaries attending the Olympic Games.
