An important question in American society can be summarized as follows: When a deranged person commits a heinous act, what is the right societal response? Is it to limit the personal rights and freedoms of everyone else (ie those who didn’t do anything wrong)? Or should it be to find ways of identifying derangement and then act upon it with their and society’s safety in mind? It is worth noting that technology is at a stage now where we can do the latter quite precisely.
