No blame is or can be positively assigned to non-action,
but blame can be attributed to any action resulting in harm or death.
That’s why lifesaving drugs take so long to get approved.
No one can directly blame the FDA for holding a drug back,
but if they let one out that kills .00001% of the recipients,
there is direct attribution.
By prohibiting propranolol for seven years while the approval process ground on (and while the drug was legal in Europe) and then proudly proclaiming that it would save 10,000 lives each year after the approval, the FDA tacitly admitted to causing some 70,000 deaths in the interim. But, not a day in jail nor a dollar in fines, of course.
