Anti-triad inspectors are the police officers most susceptible to corruption, draft anti-graft guidelines suggest. It is also suggested officers in serious debt might offer their creditors special benefits as a reward or accept cash bribes in order to repay money owed. The Guidelines on Managing the Integrity of Police Officers, which are the first of their kind, detail ranks and posts at which officers are most vulnerable to taking bribes; 18 possible reasons behind accepting bribes; and 13 indicators to spot crooked colleagues. Officers are also asked to stay alert if they are invited to dinners often or offered gifts and advantages. The guidelines, which also advise on anti-graft strategy, will be distributed to all regular and auxiliary officers next week. Some junior officers were unhappy about being singled out as likely offenders, while others said the reminders were unnecessary as there were already rules regulating conduct. Local Inspectors' Association chairman Tong Liu Kit-ming said: 'The guidelines are valuable as a reference. But to conclude the corruption problems, more scientific research is needed.' Senior Superintendent Charles Wong Doon-yee said: 'The guidelines are part of the anti-graft effort of the force. They do not mean to be conclusions to the problems but will serve as reminders for officers.' Based on results of a force anti-graft survey and advice from anti-graft experts, the draft suggests excessive gambling, extravagance, greed, unclear force policy, and the 1997 factor as possible reasons for corruptibility. Between 1992 and 1995, 65 police officers were taken to court for corruption cases. They included one chief inspector, six senior inspectors, two inspectors and 56 junior police officers. This suggests that officers at the rank of inspector are the most susceptible to bribery, followed by sergeants and constables. Detectives are also regarded to be more corruptible than uniformed officers. Vulnerable posts in the crime department are likely to be among the anti-triad squads, Narcotics Bureau and Organised Crime and Triad Bureau. Among the uniformed branches, jobs with the special duties squads - which deal with drugs, illegal gambling and vice problems - top the list of vulnerable posts. Miscellaneous inquiries teams and taskforces and marine officers were next on the list.
