“I had a case involving a 15-year-old girl recruited to shoot someone in the head,” Stockholm prosecutor Ida Arnell told AFP. “She was able to choose the type of mission she wanted, in other words, to aim at the guy’s door or his head. She chose the head.”
I expect that this might me due to functional police and criminal investigation systems. Less functional countries, which are in the majority, will likely fail to find the right perpetrator, fail to report on it, blame the crime on the wrong person, ignore the crime, etc.
