System 'learns' to spot holes to aid police, prosecutors, judges

Shanghai is testing an artificial intelligence system that helps police officers, prosecutors and judges check the validity of evidence in criminal cases, as part of an effort to prevent wrongful convictions.

Over the past month, the system has reviewed 60 cases - including homicides, burglaries and telefraud - and correctly identified 48 flaws in evidence, the Shanghai High People's Court said on Monday.
