A police officer yesterday acted out in front of a jury what he says was the moment when he jammed his finger into the trigger-guard of a weapon to stop a gunman shooting him. The re-enactment took place during the trial of Chan Kwok-ming, 44, who has pleaded not guilty to attempting to discharge a loaded firearm with intent to prevent being arrested outside Lai Lan House, Lai Kok Estate, Shamshuipo, last year. It is the second time Chan has faced a jury after his last trial was aborted on June 20 due to technical errors. Prosecutor Edward Laskey told jurors to disregard any previous publicity from the first trial. He said the central issue was whether Chan produced the gun and pulled the trigger. Mr Laskey said Chan had been carrying the self-loading pistol around in a shoulder bag when three police officers stopped him and asked to see his ID in a market just before 10.30am on October 5 last year. He said the incident spun out of control when one of the officers wanted to search Chan's bag for drugs. Senior Constable Ho On told the court Chan pushed him in the chest before whipping out a pistol from his bag. The constable demonstrated how, in his version of events, he grabbed hold of the gun in the ensuing struggle, shoved his left forefinger in the trigger-guard and pulled the gun towards the ground. Police Constable Wong Yau-fai also told the jury that after Chan had been subdued and cautioned, he had said he had hoped to find a rich person to rob with the gun in an attempt to clear a $200,000 debt. The trial before Mr Justice Thomas Gall continues in the Court of First Instance.
