I know it's a stretch to actually ask politicians to use their brains, but a thorough review of all the scientific evidence alludes to the fact that there has not been a peer reviewed study demonstrating pornography increasing the incidence of sex crimes in any nation yet studied, in fact all the data points to the contrary, that sexual crime has been reduced when pornography has increased. here's a paper on it.

in the last paragraph they say this...
In sum, the concern that countries allowing pornography would show increased sex crime rates due to modeling or that adolescents in particular would be negatively vulnerable to and receptive to such models or the society would be otherwise adversely effected has not been vindicated. It is certainly clear from our data and analysis that a massive increase in available pornography in Japan has been correlated with a dramatic decrease in sexual crimes and most so among youngsters as perpetrators or victims. We have mentioned some possible influential factors.
