I'd read about this a little before, but hadn't really grasped the full scope of it:http://www.kenny-glenn.net/
Essentially a 14 year old horifically abused his cat - I couldn't watch the videos, owning a cat myself, I felt all the pain - and posted some videos online. He's clearly got a screw loose from something, and seems to be happy about what he did.
Browsing that website though, it looks like some people have taken it too far. Whilst not forgetting that the boy was only exposed - and the cat was only saved - through the efforts of /b/, this looks like a rather unfair result on his parents, who were probably unaware of what was happening.
I wonder if we'll see more cases like this in the future?
