zeb, he's playing with the numbers. From the John Howard Society in Alberta (I looked this up earlier, before I commented, just to confirm his gross distortion of the facts). It could be 15% after only 5 years, keeping in mind that these statistics involve those who were caught and reconvicted. It naturally follows that not all are caught.

A long term follow-up study of child molesters in Canada found that 42% were reconvicted of sexual or violent crime during the 15-30 year follow-up period.
