Beijing police are to relinquish their security role at public events, leaving organisers responsible and liable for safety. Cao Dongxiang, director of Beijing Public Security Bureau's major events department, announced that it would soon be the norm for event organisers to assume control of security. Speaking at a forum in Hangzhou, Mr Cao said Beijing, Hangzhou and Shenyang were just three cities in the country with revised regulations charging organisers with responsibility for public safety. Beijing introduced regulations in 1999, identifying organisers as being responsible for safety at indoor events attended by more than 500 people or outdoor events with more than 100 participants. Most of the duties relate to drafting safety plans and helping police. But the regulation has not been well implemented and a Beijing police source said many organisers misunderstood their security role. 'In their mind, safety has always been the job of police and something that is not their business,' the source said. In practice, police have always been in charge of safety, but organisers have been asked to present details of security measures before getting approval to stage events. But increasing domestic and international security threats have put pressure on police resources and prompted authorities to limit their roles. 'In Beijing, we have 6,000 major events each year. It's obviously unsustainable for our officers to be burdened with all these safety tasks,' the source said. Yang Lixin, a professor of civil law at Renmin University, said mainland law supported the idea of organisers taking responsibility for security at their events. He said the Supreme People's Court issued an interpretation in December on personal injury compensation, saying the court should accept personal injury suits filed against organisers of social events relating to inadequate security preparation. 'Organisers should take on the main responsibility, irrespective of whether the events are being co-ordinated by an organisation or government,' he said. 'I think police realised the seriousness of this after the Miyun stampede,' he said, referring to an accident at Rainbow Bridge in Miyun county in February, in which 37 people were killed.
