It would be up to the psychologist to determine what tools or instruments they would use, whether it would be the psychopathy checklist or other kinds of instruments.
We didn't go into that level of detail in terms of the psychological evaluations of each one of these cases. I suspect that many of them, for one thing, may not participate in the administration of these things, or may have. But I don't have any knowledge of any research on psychopathy or that kind of research.
