Investigations of maltreatment of detainees, POWs and kidnapped folks are important. Each entity that hold these folks, probably have internal quality control measures to try to snuff out the people doing the harming. During war time, probably there are more instances of maltreatment. Until more data can be collected, the world listens to the descriptions of the released detainees, POWs and kidnapped folks. Hopefully investigations will increase as the war becomes less intense.
