He shouldn't have plead guilty, this case never would have stood up in court. To answer chikusho's question...
It's simple, there CAN'T be. If there is no one who is victim to this "crime", then it cannot be called a crime, in this case the only person who has been wronged is this man.
And I don't care if he IS a pedophile, this blind societal hatred towards pedophilia is sickening, and anyone who thinks that popular culture, the media, or even laws (which by the way were made quite some time ago) are clear indications of how to align your moral compass, you need to find someone who can teach you how to form opinions, because conformity and rational thought are not the same thing. Just like pedophile and child molester are not the same thing.
On another note, since I'm sure someone reading this is going "Oh, so you support rape and/or child molestation. You're a pedophile". While I don't think there's anything wrong with them; I am not a pedophile; and no, I do NOT support rape and/or child molestation. Guilt by association is nonsense and exactly the reason why no one would stand up for this man in public, they'd rather watch him be crucified than even insinuate that perhaps no crime was committed, because even saying it wasn't his - now that the media has branded him a pedophile - is seen as defending a pedophile, and therefore being one, therefore being subject to unrelenting hatred.
I would get into the deep and dirty world of power and it's lasting effect on people's opinions, but I'll shorten the argument I would need to prepare to explain why I don't have blind hatred towards ANYONE at all into this: If anyone thinks that the reason why pedophiles are such a taboo has anything more to it than a few (and I mean less than ten) men of power suddenly deciding that's what the church should teach, you are horribly mistaken. There was no grand council of infinitely wise people who under the request of god himself(if you believe in a god) decided that children and adults don't make good partners.
This is why I feel sorry for this detachment of society who are likely to be shot if they tried to defend themselves; because it was by arbitration that they are condemned, and will be for some time longer - for something they can't help.
Wow, that could have been shorter...
