Rubber bullet injury: case report with autopsy observation and literature review.

Rubber bullets are one of the less-lethal (nonlethal) weapons, which are increasingly used to incapacitate dangerous individuals, avoiding use of firearms. An autopsy examination of a man who was shot with improved rubber bullets revealed that the bullet caused pulmonary contusion. The bullet was 30 g in weight and consisted of a sponge foam nose with 40-mm diameter and a plastic body. He was not incapacitated and died of suicidal gunshot wound. The case raised a question as to how severe an injury is necessary to deter a person without causing death. A variety of rubber bullets have been used in the world, and they have occasionally produced severe or lethal injuries. A review of the literature demonstrated that the feature of injuries appeared to be related to the type of missile. It becomes more important for a forensic pathologist to be familiar with rubber bullets and injuries caused by them as the use of less-lethal weapon increases.
