Not that we don’t need scientists too, but they have a specific role that has to be formed by ethics:

“We will develop strict guidelines, which we will rigorously enforce, because we cannot ever tolerate misuse or abuse,” said the President. But, of course, for many Americans, lifting the ban on embryonic stem cell research is already an act of misuse. These are contentless words, and the President must fill in that content. Punting the questions to a group of scientists is not the answer and he is inviting an even deeper level of battle in the culture wars if the NIH comes back with ridiculously broad rules.
