[Machine Translation] There is no direct relationship between developmental disabilities and crime. However, it is undeniable that the characteristics of children with developmental disabilities tend to draw them into the world of crime. What is needed to break such a negative cycle? In this report, we thoroughly interviewed the people involved, including correctional institutions, juveniles who have become perpetrators, psychiatrists who support them, and the field of special-needs education. The author dares to cut into the taboo, and presents a solution to the problem by looking at the "facts that we don't want to see" head-on.
