Police associations are calling for a law to ban foul language against police officers after recent incidents of abuse at two protests. The Police Inspectors Association and Junior Police Officers' Association said swearing at police should be prohibited. Offensive slogans appeared at a September 3 protest, when hundreds marched to accuse police of abusing their powers and urge the commissioner to step down; and on September 18 against Vice-Premier Li Keqiang's visit to Hong Kong. Benjamin Tsang Chiu-fo, head of the inspectors' group, said: 'Being able to enforce the law in a dignified manner is important for police', citing similar laws in France and Australia. The Legislative Council's security panel chairman said such a law would not be practical. 'The dignity of the police should be built up by the high quality of the force,' James To Kun-sun, of the Democratic Party, said. 'Where there is no law against verbal insults in general, one for the law enforcers would create a double standard.'
