Justice is blind and must be seen to be blind, a leading sociologist said, amid heated public discussion over a controversial case.

Judicial bodies, especially courts, must always be objective and remain unswayed by public opinion, no mater how difficult, said Wang Ping, managing director of the Chinese Society for Juvenile Delinquency Prevention Research.

Wang was speaking against the background of the case involving Li Tianyi, son of Li Shuangjiang, a famous army singer.
