Entropic: As you describe it, the LAPD study is worthless in establishing a causal link between kiddy porn and pedophilia as the population sampled are pedophiles, and did not include non-pedophiles. Only an unbiased sample of both groups would have a chance of establishing any connection that is statistically reliable. In fact, the Feds have been unable to produce for the Courts any valid study that makes a link between pornography and sex crimes. What other reliable studies exist on the subject that have been submitted in court show no causal connection. Other variables impacting on pedophilia, as you described it, were likely not included, such as the pedophiles child and family history. From a statistical point of view it would have been equally invalid to associate pedophilia with wearing shoes, drinking water or beer, walking, driving, or reading ability.
