Law-abiding video disc manufacturers will not be made scapegoats over proposals to stamp out piracy and copyright infringements, an official said yesterday. Only those who commit serious crimes will be prosecuted under an amendment to the Organised and Serious Crime Ordinance, which will cover such infringements. Philip Chan Kwan-yee, Principal Assistant Secretary for Trade and Industry, told a Legco subcommittee studying the proposed amendment that the legitimate industry will not be affected. Concerns were raised recently by a number of manufacturers about whether they will become scapegoats if they are found making video discs without licences. The manufacturers said they sometimes found it difficult to verify whether the authorisation they received from copyright holders was authentic. They blamed the Government for the lack of guidelines. But Mr Chan dismissed this claim and warned the industry not to 'confuse public opinion' over the issues of law enforcement and verification. 'There is already an exemption clause in the ordinance to protect innocent manufacturers. If there is a problem it already exists. The amendment is another matter on the question of copyright verification,' he said. The exemption clause says people are not liable if they do not know copyright is being infringed.
