Legalizing child pornography is linked to lower rates of child sex abuse EurekAlert Science News
"Results from the Czech Republic showed, as seen everywhere else studied (Canada, Croatia, Denmark, Germany, Finland, Hong Kong, Shanghai, Sweden, USA), that rape and other sex crimes have not increased following the legalization and wide availability of pornography. And most significantly, the incidence of child sex abuse has fallen considerably since 1989, when child pornography became readily accessible - a phenomenon also seen in Denmark and Japan. Their findings are published online today in Springer's journal Archives of Sexual Behavior.
The findings support the theory that potential sexual offenders use child pornography as a substitute for sex crimes against children. While the authors do not approve of the use of real children in the production or distribution of child pornography, they say that artificially produced materials might serve a purpose.
Diamond and team looked at what actually happened to sex-related crimes in the Czech Republic as it transitioned from having a strict ban on sexually explicit materials to a situation where the material was decriminalized. Pornography was strictly prohibited between 1948 and 1989. The ban was lifted with the country's transition to democracy and, by 1990, the availability and ownership of sexually explicit materials rose dramatically. Even the possession of child pornography was not a criminal offense.
The researchers monitored the number of sex-related crimes from Ministry of Interior records - rape, attempted rape, sexual assault, and child sex abuse in particular - for 15 years during the ban and 18 years after it was lifted.
Most significantly, they found that the number of reported cases of child sex abuse dropped markedly immediately after the ban on sexually explicit materials was lifted in 1989. In both Denmark and Japan, the situation is similar: Child sex abuse was much lower than it was when availability of child pornography was restricted."
Although about child pornography in particular, it has cross-applicability. If you give people a sexual outlet that isn't crim-erelated, they'll take it. But if you deny them an outlet, they'll become victimizers.
Inference then being, if Norway makes illegal sex involving the homeless, the homeless aren't going to become celibate but rather have sex criminally.
