The obvious reasons I mentioned,
Somebody has tried it before.
Do you really find it that much of a stretch to think that people would abuse the legal status of this stuff?
People are into child abuse, there's nothing new in this, some of these people are probably into loli as well and some of these create images based on this.
Image manipulations, drawings based on, at what stage do you put a line at "This is child porn" and "This is fine, it's just a drawing".
So, yes, the grey areas have to be covered. The law has to be vague because the subject is vague. It has to be this way to prevent weaknesses and exploits.
That's basically the only reason the law exists. Nobody forced this guy to possess the material, it's illegality is clear to anyone with the internet.
And what's the downside of this law? Some people on the internet can't jack off to a certain material without the low risk of being caught?
Guys, listen, I appreciate people have needs, but really?
You want to remove a law that prevents legal porn based upon the abuse of children so that you (Or other people.) can get off to images you found in the internet?
No, it's not "Hurr, thought crime", there's no law against thinking about it, don't be ridiculous. It's simply a case where the benefits are fewer than the abuses.
He committed a crime, that's the law. It's there for a reason.
I know we all like to think we know better, but, the law has been established years ago by people much more knowledgeable on the situation than anyone here. And if you think about the potential implications of not having it, you'll see why it stands.
