Pareto principle and crime

The pareto principle may well apply to crime prevention too: "“Billions of dollars in criminal justice costs are wasted each year on people and places with almost no risk of serious violent crime,” said Sherman, “while the high-risk targets receive far too little attention.” Citing rising homicide rates in Philadelphia since 2002, his research shows how more rehabilitation for a tiny number of offenders may have been able to prevent many of the murders."
