Legal experts have urged the authorities to stop evaluating law enforcement by the number of cases they handle.

Under the current appraisal system of law enforcement in China, performance is evaluated on the number of criminal cases solved and the number of suspects detained or prosecuted.

The current evaluation system encourages officers to use any means necessary, some of which may be illegal, to inflate arrest and conviction numbers, said Zhao Bingzhi, dean of the College for Criminal Law Science at Beijing Normal University.
