High crimes

Stuart Buck points to this piece from Science Daily

Using data across a wide range of research, Sherman shows that most crime is committed by a small fraction of all criminals, at a tiny fraction of all locations, against a tiny fraction of all victims, during a few hours a week. By focusing police, probation, parole, rehabilitation, security and prison resources on these “power few” units with the most crime, the study shows how society could stand a far better chance at crime prevention without raising costs.

and asks:

I wonder how one is supposed to identify the "small fraction of all criminals" and the "tiny fraction of all victims" ahead of time, rather than in hindsight.

I wonder what we're supposed to do with them if we do manage to pick them out. Can one preemptively deploy the power of the state against people who seem likely to commit a lot of crimes? I sure hope not.
