A teenage girl convicted of drug trafficking was criticised by a judge yesterday for saying she wanted to go to jail rather than a training centre as the sentence would be shorter. Ip Lei-kei, 16, was 'not able and not willing to learn from her mistakes', said Deputy District Court Judge Josiah Lam Wai-kuen before sentencing her to three years in jail. Ip had earlier pleaded guilty to one count of trafficking dangerous drugs at her flat in Sha Tin on March 17. Ip had told Judge Lam: 'I believe sending me to prison would be the most striking punishment for my mistake. Although a training centre provides education and training discipline, the longest period to stay there could be three years.' A sentencing report had recommended she be sent to a training centre. 'But I hope I can be released from prison as soon as possible and get back to my studies,' she said. In sentencing, Judge Lam said Ip's attitude was pitiful, since he believed she would have benefited more from a training centre, where counselling, education and vocational guidelines were provided. She had simply assumed that a jail term would be shorter after being remanded for four months, the court heard. It would be a waste of time and resources to force Ip to attend a training centre, the judge said. Police found more than 21 grams of ketamine at Ip's home, worth about HK$2,600. She later admitted helping a schoolmate sell and deliver drugs.
