Neurolosit claims to find "where evil lurks" in the brain

>>“There are cases where someone becomes criminal as a result of a tumour or an injury in that area, and after an operation to remove the tumour, that person was completely normal again"

I'd love to find out more about these cases. I know PFC injuries can result in lack of self control, but criminal behavior due to a brain deformity. That's a pretty bold claim. Can early detection lead to lower crime rates?
