A police officer in charge of collecting evidence for lawmaker Wong Yuk-man’s assault trial told the court on Tuesday that he could not verify whether the submitted news footage had been modified.
Wong is facing charges of common assault for allegedly throwing a glass at Chief Executive Leung Chun-ying during a Legislative Council question-and-answer session in July 2014. He has pleaded not guilty and is representing himself.
Last week, Leung testified in court, making him the first Chief Executive to do so while serving in office.
In court on Tuesday, Wong objected to the submission of news footage relating to the incident and cross-examined Kwan Sin-yuen, the police officer who was responsible for obtaining the clips.
Wong asked Kwan whether it was true that there was no way to verify if the TVB clip had been modified or if the smashing sound of the glass or the shards on the ground could have been edited in afterwards. Kwan agreed and said he could not confirm whether parts of the clip had been edited, RTHK reported.
Kwan said that Leung did not display any reaction after the glass smashed. He also agreed with Wong that Leung slightly turned towards the right after the incident, rather than “freezing” on the spot as Leung claimed earlier.
Wong objected to the prosecution’s application to list police officer Cheng Hong-yip – who helped obtain the news footage submitted to court – as a computer forensics expert. Wong said that Cheng was under-qualified and had never testified as an expert in the area, but magistrate Chu Chung-keung granted the prosecution’s request after reviewing Cheng’s experience.
