I wasn’t exactly able to find him say anything about gathering data about CP sex offenders, however I was at least able to find a video of him saying that there is no conclusion yet: youtu.be/2UvKgsi-kDg?t=318

I thought I heard him say that gathering data was very difficult as people would have to admit to offending. Maybe it was because I kept on hearing him talk about problems with studies sample sizes but that doesn’t matter.
