Résumé
"The dark figure of crime, or the incidence of unreported crime, was established over forty years ago by the President’s Commission on Law Enforcement and the Administration of Justice. It was sizeable then (representing one-half or more of sex offenses and simple assaults) and it remains sizeable today, suggesting that the important changes that have occurred in policing have not produced any substantial changes in citizens’ willingness to reduce this figure."--Conclusion.
