"not show any ... significant increase" for homeless/unemployed offenders? Or all registered offenders as a whole?
Res Ipsa wrote:That increased rate of reporting could offset a decline in the rate of the incidence of child abuse. Or that, because law enforcement has access to the registers, they were able to locate and arrest repeat offenders at a higher rate. Again, this increased efficiency could offset any decline in the incidence of child abuse. I looked for, but could not find any studies that looked at those kinds of potential effects. (Not that my research skills are perfect....)
It is a good possibility, but is there any evidence that reports are increasing? You told me, "However, a big problem with that -- there's substantial agreement in the literature that sex crimes are significantly underreported"
Res Ipsa wrote: At any rate, I don't see anyone suggesting that legalizing kiddie porn would be an acceptable way to reduce sex offenses.
Of course not. I thought I made it clear in my post above. The authors do not approve porn, it is not an acceptable way to reduce child abuse. My only point was that we don't see studies showing a "significant decrease" of child abuse because of the sex offender registries.
Res Ipsa wrote:The problem with that study is that it simply showed correlations without exploring other possible causes of the decline. It also looked at aggregate measures of sex offenses without considering that exposure to pornograpy can have different effect on different individuals. .
It is a study published in a respected Journal. For you what could be another possible cause? If you know of another possible cause please let me know because it could be very important,
but according to the study, "In comparison with our findings for the sex crimes mentioned following democratization and porn availability, the number of societal crimes of general murder, assault, and robbery rose significantly. Murders associated with robbery or with other non-sex related motives increased sharply (t= -6.8, df=20, p\.001) (Fig. 2). Murders associated with sex related matters—small in number at any time—did not increase (t= -0.3, df=23, p=.77) (Fig. 2). The number of reported sex related crimes decreased significantly from the pre-switch period to the post period, (t=5.3, df=32, p\.001), whereas the number of reported nonsexual crimes increased signifi- cantly (t= -19.72, df=35, p\.001) (Fig. 3)"
Again, I am not saying porn is the solution because we cannot legalize an evil to fight another evil, but my point is that you won't find the same numbers in sex offender registry studies.

Here is a list of studies showing porn (in general) does reduce rape, but we have no such list about the sex offender registry
