The United Nations has released an opinion survey showing that eight in 10 Afghans do not think the Afghan National Police are ready to take charge of law and order.
Sixty-eight percent of those surveyed said foreign troops should stay for now.
The survey underscores concerns about the transition to Afghan responsibility for security by 2014, when foreign troops are due to leave.
The UN report says police corruption remains a significant concern among Afghans.
There also are concerns about police misconduct like excessive use of physical force, drug-taking, perceived bias, and disrespectful treatment.
More than half surveyed said they think Afghan police are loyal to their own clan.
A majority said filing a complaint against a police officer would not help.
