上周一江苏省昆山市震川路于海明致刘海龙死亡案备受社会舆论关注。昆山市公安局调查后发布通报称，于海明的行为属于正当防卫，不负刑事责任，公安机关依法撤销于海明案件。请看本报昨日的报道：

A cyclist has been exempted from criminal liability in a case that involved the death of a driver in Kunshan City, East China’s Jiangsu Province, local police and prosecutors announced Saturday.

The incident happened at around 9:30 p.m. last Monday at a crossing in Kunshan, when Liu Hailong, 36, driving a BMW, almost crashed into Yu Haiming, 41, who was riding a bike in the bike lane. Liu stepped out of the car and attacked Yu’s neck, waist, and leg with a long knife, but Yu grabbed the knife during the fight and stabbed Liu to death.

Based on the investigation and in accordance with relevant provisions of the Criminal Law, police said that Yu’s act was regarded as justifiable defense and Yu should not bear criminal responsibility.

报道中的justifiable defense就是“正当防卫”，也可以说justified defense, 防卫过当是excessive defense.
