Now that Chris Langham has been convicted, I can write what I've wanted to write since his arrest. What is it with these people who, when they've been found with depraved dowloaded images of children, start pleading all sorts of excuses in supposed defence of their behaviour? Research, abuse as a child, blah blah blah.
You'd have to be dense in the extreme not to be aware by now that downloading such images is a strict liability offence. You download them, you're guilty. End of story. And that means there are no circumstances - none, ever - in which one should do such a thing.
So anyone who downloads them and then offers a spurious excuse is either a moron of the first degree, or someone depraved enough to be incapable of resisting the urge to look at such images of children.
Chris Langham is clearly not a moron.
