That right there is all I need to know. 17 permanent injuries and one death for a supposedly nonlethal method.Such "kinetic impact munitions" are meant to cause pain but not serious injury. They are expected to produce contusions, abrasions, and hematomas. However, they may cause bone fractures, injuries to internal organs, or death. In a study of 90 patients in Northern Ireland, one died, 17 suffered permanent disabilities or deformities and 41 required hospital treatment after being fired upon with rubber bullets.
