Dilemmatic Situation

In the news, the mother left her baby in a locked car for eight hours, which leads to the death of the baby. Some pople believe that she should get the jail time, while others claim that the death od her child is punishment enough. It is really a dilemmatic situation. Personally speaking, I insist that the mother should be tried.
For one thing, it is her lapse that makes the baby die. She should be pubnished by law though she has been punished of losing her child. She is the guardian of her child. Therefore, the mother is fully responsible for protecting the child except the accident. But it is obvious that her neglifence causes this tragedy. So I hold the view that the mother should be tried to receive proper punishment.
Also, in the past 10 years, there have been many similar cases happened and most people have been charged for their lapses. Under this circumstance, there is no reason allows the mother to escape from the punishment of the law. And it can warn people of being more careful about their babies as well.
Based on all above, I think the mother should be tried and receive proper punishment but taking her sadness of losing daughter into account.
