How exactly is Families SA responsible for this child attacking the animal? Did they make him do it? Did they take his hand and hit it against the animal?

If this child was in the care of his parents i'm sure you'd blame them too for this child doing this.

Why shouldn't the child visit his mother? Chances are it was organised before he did this. Chances are it's for christmas. Wouldn't you want to see your child if they were in care, regardless of what they have done? If your child was in care you'd expect them to pay the bill to send them to you. So how is this any different?

It's not, you're nit picking.
