Risking a lot by commenting on this... but what he defended was that possession of images should not be illegal, only the act itself should be illegal.
He used as an example of how the law was bad, that if you witnessed someone doing the act, and filmed it to hand over as evidence to the police, you would end in jail too, something that is obviously unfair.
