Almost 1,000 people turned out in Manila yesterday for a memorial service for the victims of last week's tour bus tragedy, with appeals for justice over the botched handling of the hostage crisis that led to the deaths of eight Hong Kong tourists. There has been a storm of criticism from Hong Kong since last Monday's carnage in which authorities' mishandling of the crisis seemed to enrage the hostage-taker, former police officer Rolando Mendoza, who shot the victims before he was killed by a police sharpshooter. About 250 police officers were among those who attended the Mass, which was offered in front of the Quirino Grandstand, the site of tragedy. 'This terrible case is also calling out to heaven for justice,' Bishop Broderick Pabillo, Manila Auxiliary Bishop, said in his homily. 'Not only the Chinese are calling for a just and swift investigation of this case. We Filipinos demand the same from our officials. Bring out the truth, let those who are responsible, whoever they may be, be held accountable. No whitewash. No scapegoats. Let there be new life for our justice system.' The Mass was preceded by a ceremony performed by Buddhist monks from Taiwan. China's ambassador to the Philippines, Liu Jianchao , said that a fair and thorough investigation would help relieve the anger and loss of Hong Kong and Chinese people.He told the South China Morning Post that 'both the Chinese and Philippine governments share the aspiration that we should focus now on the investigation, which means a thorough, fair and credible investigation that will bring further relief to the [families of] people who lost their lives'. After laying a single white rose on a dais in front of the site of the incident, he added, 'I'm really touched by the service.' Liu said, 'We appreciate everything the Philippine government and the president himself have done' in the aftermath of the hostage-taking. In his homily, the prelate noted that Mendoza was a veteran policeman and he had a special message for the authorities: 'Did his service not ingrain in him respect for others and respect for life? New life for our police and armed forces is not just to get more sophisticated arms or to get more training. It is above all to have deep love and respect for human rights and life itself.'
