Her defense is insanity. I think she was/is insane and deserves a fair trail, which she didn't get the first time.
And even IF she is found to be not guilty due to insanity, I hope she is locked up her entire life because society cannot afford to pay the price just in case she goes off of her meds again and kills/harms someone else.
Someone HAS to protect society from these "loonies". Once again, it is up to our justice system to do the right thing.
Will the system prevail?
Another trial is a waste of taxpayers money and she won't be any less guilty. Her husband ought to be on trial.
