Tapes protect rights of suspects

Dealing with a growing number of cases amid China's anti-corruption campaign, Shanghai prosecutors are making every effort to ensure that "justice is not only done but is seen to be done".

In a recent report delivered to Shanghai's legislators, Chen Xu, the city's chief procurator, said the number of bribery and corruption cases filed in the first half of 2014 grew by 12 percent year-on-year.

From January 2013 to June 2014, the prosecutor handled 512 duty crime cases involving 643 people, 18 of whom were county level or higher officials.
