Self-defense debate rages after knife attack

A knife attack in Kunshan, Jiangsu province, on Monday that involved a gang member, road rage and the victim becoming a suspect, has attracted attention online and generated heated discussion about what constitutes justifiable self-defense and excessive force in China.

On Monday, an electric bike rider surnamed Yu was waiting at a traffic light at the intersection of Zhenchuan Road and Shunfan Road when a BMW sedan suddenly veered into the nonmotorized vehicle lane to avoid waiting in line to turn right.

Surveillance video footage showed two people getting out of the car and confronting Yu - apparently after the car struck the bicycle. As the three were talking, a third man, surnamed Liu, 36, got out of the car and attacked Yu.
