The row between journalists and police intensified yesterday after the police chief refused to withdraw his 'black shadow' remark, used to defend the force's tactics during Vice-Premier Li Keqiang's visit last month. Commissioner Andy Tsang Wai-hung had said in a Legislative Council meeting that an officer believed to have blocked a television camera was instinctively reacting to a 'black shadow' rushing towards him. But Now TV had recorded someone saying 'this is a reporter, watch him', shortly before the camera was blocked. Lawmaker Kam Nai-wai asked Tsang to retract his remark, but he refused. 'I will not make further comment on the 'black shadow' remark, therefore I will not retract that,' Tsang said, adding that he did not want to affect the Independent Police Complaints Council investigation. Many reporters wore black yesterday after a call from the Hong Kong Journalists Association. Some who wore T-shirts with the phrase, 'I'm not a black shadow' - mocking Tsang - were barred from the press gallery. 'I think this is ridiculous. My T-shirt only says, 'I am not a black shadow'. I don't see any political stance,' said Ho Ka-tat, a committee member of the Hong Kong Press Photographers Association, who was barred from entry. A Legco secretariat spokeswoman said the reporters had been rejected under section 12 of Legco's Power and Privileges Ordinance, which states that no person shall display any sign or message on any item of clothing in a press or public gallery. Some reporters complained to security panel chairman James To Kun-sun, who ruled that reporters were not displaying any message. Reporters were later allowed into the gallery. Outside Legco, about 60 protesters from the pro-government Federation of Trade Unions clashed with lawmaker 'Long Hair' Leung Kwok-hung, who later accused them of hitting him with a banner. About 30 retired policemen demonstrated in support of the police. Separately, more than 2,000 people joined an online campaign to urge support for the news media by buying newspapers yesterday. This was in reaction to an unofficial police protest calling for a boycott of newspapers and for people to wear white, which drew 4,500. A survey by Chinese University's school of journalism and communication showed 40 per cent of 663 residents thought Hong Kong had sufficient press freedom, down 10 per cent from last year. About 60 per cent thought the press arrangements during Li's visit were not appropriate. Meanwhile, tourism sector lawmaker Paul Tse Wai-chun said he had filed an assault complaint at Central Police Station against People Power lawmaker Wong Yuk-man who was seen throwing a T-shirt with a June 4 pro-democracy motif into Police Commissioner Andy Tsang Wai-hung's face at the end of a Legislative Council security panel meeting on August 29.
