It is exceedingly rare for a person registered as a sex offender to be charged with a new sexual offense, reports The Sentinel of Carlisle, Penn. Of the 75 charged sex crime cases in Cumberland County in 2016, only two were committed by a person listed on the sex offender registry, according to a Sentinel analysis. And just six of the more than 300 charged sex crime cases in Cumberland County between 2013 and 2016 involved a person listed on the sex offender registry.
“For whatever reason, people who are on the registry have a very low recidivism rate,” said Emily Horowitz, professor of sociology and criminal justice at Saint Francis College. The newspaper reviewed more than 450 sex crime cases in Cumberland, Dauphin, Perry, Franklin and Adams counties in 2016 and found only 15 cases where the defendant was on the registry at the time of the offense. More than 96 percent of all sex crime cases in those five counties involved defendants who were not on the sex offender registry. Cumberland County District Attorney David Freed said the low number may indicate that registries reduce recidivism.
