If I kill a 98 years old person, is the age of the eldery a mitigating factor? I think the same logic should apply in this case.

Of course not - you are talking about human beings. Even though I'm a pet/animal lover, I don't agree with your logic.

This woman screwed up big time - I'm sure it was an accident, but a big one - I don't think she should get off with simply a lecture - truthfully, she should probably step down from her role, but I don't think she should go to jail.
