Law requires the HKSAR to improve medical and health services by formulating policies to develop Western and Chinese medicine. Healthcare is provided by the government in the nature of "grace": the Accident & Emergency service and the in-patient (general acute beds) service provided by the Hospital Authority charges HKD180 per visit and HKD120 per day (plus HKD75 admission fee) respectively. 95% of Hong Kong people depend on the in-patient service provided by the public sector and 30% on the out-patient service provided by the public sector. Criticism of the police Allegations of police brutality Human rights groups have accused the Hong Kong Police of using heavy-handed tactics on non-violent protesters. In 2002, Amnesty International cited the use of excessive force in an incident at Chater Garden where more than 350 police and immigrations officers stormed a group of 200 protesters.

In 2002, a group of Falun Gong practitioners who were protesting outside the Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region were being forcibly removed from the street by Hong Kong Police with heavy-handed tactics. All were later charged with the offence of Public Place Obstruction. The Falun Gong defendants contested and appealed to the Court of Final Appeal.

In 2008, police sergeant Thom Wing-hong punched a man in custody, Lik Sin-wan, in the head after the two argued over the way to conduct Lik's search.
