From the other countries in the literary works on criminology plus the fresh popular press, recidivism basically form another type of offense the amount of time once launch away from prison.
Webster indexed the new Langevin shot try larger in the beginning. His class got rid of any individuals from the analysis whoever criminal history records was destroyed or purged about justice program immediately after 15 many years getting decreased the latest criminal activities or charges.

The typical rapist got dos.5 sex criminal activities on their number through to the crime that delivered your so you’re able to Bridgewater. The little one molesters averaged 3.6 intercourse offenses before the offense one triggered municipal connection. Using Lengevin’s method, the newest recidivism pricing for both groups would have been almost one hundred %.

Of the 9,603 guy molesters regarding shared cohort, the pace was a dozen.7 %.
