If you were to ask most people to name the least dangerous, most beneficial branch of the Federal government, I suspect many would name the Food and Drug Administration. After all, the desire to have a safe and clean food and water supply is the #1 argument fielded in favor of a strong regulatory state. Those whose family members might have benefited from drug treatments or other therapies banned by the FDA might not view it in such a positive light, of course. Still, even there the FDA's reputation is one of being overcautious in keeping Americans safe on average -- though in effect they condemn many to death who might at least have a chance with some experimental therapy.
Should your opinion of the FDA be roughly aligned with this view, you will find this report in Scientific American to be shocking.
