Police officers taking video statements from suspects are to be protected from being unfairly identified. Copies of the tape, given to the suspects, will not show the officer's face, although the face will be included in copies going to the force and defence lawyers. The recording system, which uses two cameras, is now in operation at 60 video-interviewing rooms. 'The defence lawyers may want to look at the officer's facial expression, like whether he looks very harsh during questioning', said Chief Inspector Ma Ping-yiu. 'But the suspect will not be given a copy, in order to protect the officers,' he said. Senior Superintendent Clarence To Chun-wai said that video statements, which are now reserved for High Court and District Court cases, might be expanded to magistrate's courts. Police figures show there were challenges to 15 per cent of video interviews put forward in High Court trials in 1997. Where interviews were not recorded on video, 33 per cent were challenged.
