I don't know what exactly the parent poster had in mind about FDA, but a commonly seen argument is that delaying a drug for a year by requiring more tests saves X expected lives (more chance to discover adverse effects), but also costs Y lives (those who would've been saved during that year), and that FDA are motivated by political reasons to act to ensure safety even in cases when X is significantly less than Y - thus, in effect, killing many people.

But that's not my point to make, so I can't give specific examples.
