Axe Chops off Toddler's Leg--Mother was just a Bystander

A 21 year old mother in Australia chopped her toddler son's leg off with an axe--her "punishment?" Looks like a stay in a church run psychiatric group home. Luckily, the police were compassionate to this young mother--after all, why console the kid who just had to have his leg reattached when his mother had to suffer through this horrible ordeal? Apparently, the mother is only being held until March of next year. So in Australia, this is what constitutes justice if you are female--wonder what would happen to a man who chops off a toddler's leg if the Aussies are already up in arms if a man sits next to an unaccompanied minor on a plane? Thanks to reader,Trevor, for pointing out the article.

Update: Well, here is the answer to my question about justice in Australia for men--here is a man who had the audacity to drag around a tree branch--he got four months in jail--thanks to commenter Dave for pointing out this absurd tidbit.
