ORIGINAL SOURCE

Although convicted sex offenders raise justifiable concerns about public safety, studies indicate that many of them don’t return to their criminal ways. Researchers are attempting to come up with statistical tools that courts can use to decide who should stay behind bars and who should go free.

Data from several long-term studies of 4,724 sex offenders released from prisons in the United States and Canada after 1980 show that after 10 years, one in five had been arrested for a new sexual offense, says psychologist R. Karl Hanson of the Department of the Solicitor General of Canada in Ottawa. After 20 years, that figure rose to slightly more than one in four. Among men who had victimized children in their own families, an even lower fraction—about 1 in 10—committed a new sexual offense during the first 20 years after release from prison.

Hanson, however, estimates that close to half the released sex offenders eventually commit another sex crime. “Most of their offenses are never reported to the authorities,” he said.
