-33- F.3 Other evidence

91. PW13 is Professor Lau Chi-pang. He was called as an expert in history to give his opinion on the Slogan. As the Defence had also called two experts on this topic, we consider that it would be convenient to set out all the expert evidence relating to the Slogan in section F.4 below.

92. The statement of PW14 (Senior Inspector W M Cheung) was admitted as P228 and the certified English translation P228A under section 65B of the Criminal Procedure Ordinance, Cap 221.

93. His evidence was that his team had viewed a total of 2,177 videos out of which he himself had viewed 825. He was able to separate the videos into 8 categories.

94. PW15 (Dr Tsang Cheuk-nam) is a forensic scientist and his statement was marked as MFI-1. He said he was tasked on 21 July 2020 to determine the speed of the Defendant’s motorcycle.

95. He had viewed the footages and was able to say that the speed of the motorcycle was about 20 kph when it was stopped by the police. He was unable to tell from the footages whether the Defendant accelerated or decelerated. His calculation was based on the time on the camera and the length of the motorcycle.
