Crime or life science? What's your view? I'm a total supporter of Eugenics in theory, I'm unsure how to put it into practice but I believe that the majority of misery created by anti-social behaviour and other equally troubling behaviour arises mainly from not simply neglect or abuse and its impact across the life span but the genetic inheritance passed on through the years. Bad or recessive genes combine with environment with predictable results.
It's a pressing problem, I've read and considered research that all the existing therapeutic interventions in the form of health and social services in the UK will be totally ineffective with certain hard core populations since they are so cognitively challenged the chances of responding to any intervention is remote.
Interventions could care for these individuals, mitigate for them the consequences of their actions to a certain extent (which may or may not involve injustice or at the very least disatisfaction to others) but it will not rehabilitate them, which may or may not happen with the full passage of time and further maturation towards old age.
