The police continue to have the poorest public image of the five branches of the disciplined services, according to a survey. The force's performance last year was chosen as the worst of the services by 46.6 per cent of respondents in the poll. The police also ranked worst in the 2000 poll. The Correctional Services and Immigration Department came second and third respectively in giving the worst public impression, according to the Democratic Alliance for the Betterment of Hong Kong, which conducted the survey. The Customs and Excise Department came in fourth, while the Fire Services Department was judged to have the best public image. Although the percentage of people who said they were most impressed by the police increased from 21.4 per cent in 2000 to 24.2 per cent last year, those who found the police friendly dropped from 27.3 per cent to 20.1 per cent. The manner of immigration staff also failed to impress the public, with those describing their attitude as bad rising from 24.1 per cent to 28.6 per cent. Party legislator Lau Kong-wah said all branches of the disciplined services should improve their manner and quality of service.
