Canada did, as I mentioned, in the Butler case—and there have been various decisions since then—try to draw the line on what is legal and what is not legal, particularly focusing on violent pornography as being illegal and other types of pornography mostly being legal. Of course, child pornography is illegal all around.
Canada used to prosecute some violent pornography, but now pretty much has stopped doing that because it's become virtually impossible. With the Internet, you can now put in certain key words if you're looking for certain types, such as “rape” or “forced”, and you will get a plethora of violent pornography. It is pretty much impossible to prosecute anymore compared to years ago when Canada was primarily focusing on pornography that was brought across the border from the U.S. and that was violent. So a lot of it what is technically illegal in Canada is no longer prosecuted.
In the United States, there isn't such a division, and violent and other kinds of pornography are legal. If you use certain select words, you can find virtually any type of pornography on common sites that are now available, except child pornography, which, as mentioned, is part of an underworld that you have to really seek out. But if you go to some of the most common sites, and I can give you the names of them, and maybe I should, but let's say it's videos and you put in the word “forced”, you will see hundreds of videos that show rape. That is no longer [Inaudible—Editor].
While Dr. Fisher mentioned the work of his former graduate students, insofar as people are attracted to this type of pornography, in the published version of Boeringer's study and other studies, they do show that a significant minority of men in the general population are sexually aroused, particularly by violent pornography—and that is the best single risk predictor. Even though none of the individual risk predictors are good in and of themselves or predict very highly, you have to take six or seven of them. But if you were only to select one, then sexual arousal to violent sexual images would show the highest correlation with actual sexual aggression.
