I wish more people understood this!
I think pertinent to this case is the question: Did Rusty, mom in law, anyone, make sure Andrea took her meds? No. In their insanity it was about Andrea "doing her duty".
Like some others have said, everyone involved (all of us) bear responsibility for not watching out for those children and allowing a pyschotic to be alone with 5 children.
She killed them, but if I was on the jury, I would not vote for the death penalty.
