I guess it depends what type of crime they are convicted of. This is a very delicate line to balance. Essentially they are lowering the punishment for women who are mothers. If a mother knowingly commits a crime as the punishment stands today, then it stands to reason the ones on the verge of doing that will be encouraged to recieve less of a punishment in the future. Also it depends if there is a father on the scene too. If he is then why should the mother get an easy ride as its not affecting the child if s/he has a father.
