"Stuart Newman: Dr. Jaenisch has argued very strongly against full term cloning, and as developmental biologists he and I know the reasons that this should never be attempted. But there are many people out there, bioethicists who are saying, well, we take risks every day in our lives. If it's risky to have a cloned child, well, so be it. We go out and drive our cars, right? We breathe the air. So let's take these risks. And this is crazy. But apparently otherwise responsible bioethicists are advocating this. And to my mind, this is going to happen; it's virtually inevitable unless legal restrictions are put in place. I disagree with some of the very punitive criminalization of scientific activities and therapies from abroad in the proposed Brownback legislation. I think something has to be done about that. But on the point of prohibiting embryo cloning, I think that it must be done, or we'll all wind up in a place where we don't want to be."
