In the first extensive study of the causal/correlative relationship between the use of pornography and sexual offenses, researcher Anthony D'Amato (of the faculty of law at Northwestern University) has concluded that rape statistics have declined 85% while availability of pornography rose significantly throughout the USA over the preceding 25 years.

So it is quite interesting to see that the British government has decided to respond to this study by cracking down on pornography in a manner likely to backfire quite spectacularly (as well as infringing seriously on the right to freedom of speech).
