basically this is just another case of people needing to point the finger at someone or something in order to fell that they have solved a problem and are therefore safer. however getting rid of any source of catharsis, and that is exactly what pornography is, can make matters worse in the vast majority of cases. if say for example i videotape myself being violently raped and distribute it in any form, i am basically going to be classified as a criminal because of an act that harms absolutely no-one in any visible form. I would also like to add that these materials becoming illegal may strngthen thier appeal by making them tabboo, in psychology this is called the forbidden fruit phenomenon if I remember correctly. I know someone personally who enjoys engaging in sexual acts that some would describe as brutal and i do not think this person is any more likely to go on some sexually driven killing spree than say, the mailman. so what to do? do we all start fearing the mailman? no, of course not, that would be a dangerous level of paranioa. eventually they are going to run out of things to blame and will have to accept that there is no simple answer to why some people do the things they do.
