What is wrong with our justice system!?

This is more of a rant

What the actual f**k is wrong with our justice system!? Today I read that a 26 year old mother beat her 8 month old baby with a kitchen utensil and threatened to throw her over a balcony. She walked away with a two year good behaviour bond and a $500 fine, because the judge said "the child's physical injuries are likely to resolve". Not long ago there was a 24 year old man who raped a 7 year old girl and the defense argued it was only "momentary" and "he let the girls escape". The judge sentenced him to five years with an eligibility for parole after 20 months! There are so many other cases like this here in Australia. Where there has been a disgusting act of distrust against an innocent child and the offender walks away with a minimal sentence, or no sentence at all! Our justice system is lacking. There is something seriously wrong with it. I feel like we as parents are being let down by the system. And our children are being let down.
