Democracy Now had a story on this a few days ago. While I certainly am adamantly pro choice and absolutely support whatever means that a woman opts for in order to have an abortion, it also is important to give credence to the fact that this method can, in some instances, have complications that are not simply slept off overnight. Medical professionals are still going to need to be involved so to maintain the safety of the abortion, otherwise things could go sour in some cases.
