Parents brought their children with them to a protest against comics yesterday. The rally was sparked by the jailing for life on Saturday of a group of teenagers, said to have been influenced by violent comics, for the murder and torture of a boy. Protesters said the Government should insist publishers put warnings on the covers of violent comics. One mother, with children aged five and eight, said she did not allow them to buy such comics, but they could borrow from schoolmates'. 'They're still children. They're not mature enough to make a judgment. The tragic incident really scared me and I feel sorry for the schoolboy, his parents as well as those teenagers who have to spend the rest of their life in jail,' she said. The protest was organised by the Democratic Alliance for the Betterment of Hong Kong. Protesters tore up comics before handing them in at the Central Government Offices. They urged the Government to review the Obscene and Indecent Articles Ordinance and order warnings to be put on comics. On Saturday, Mr Justice Michael Wong Kin-chow urged parents, authorities and the Government to curb an undercurrent of youth violence which led to the killing of Luk Chi-wai, 15. A 13-strong gang was found guilty.
