You take the story at face value Anchorman ? Yes it seems a harsh sentence but is that story the whole truth? I put money on there being a hell of a lot more to it.
It's true that some people lead chaotic lives and are unable to look after themselves, usually due to mental health/disability or addiction issues, but the defence never raised that.

The fact that the Nationalists are trying to use this story as a political weapon says it all - it's not about compassion - it's about politics!
