People who do such stupid and reckless things are not generally haunted by guilt. I would like to see her prosecuted.
Awhile back there was an article about a man that left his young son in the car asleep while hunting. The child got out or something and died. The judge would not listen to the prosecuter. She felt the same way you did I guess and found him guilty. Evidently her sentence wasn't stiff enough though. The dad couldn't live with what he had done and went back to the same spot and sentenced himself to death. Neither you or I know what this woman feeling. Only she and God know that.
