If FDA had taken private property without just compensation we would be (rightly) complaining. Certainly there is no way the Agency can inspect every one of the hundreds of thousands facilities within their jurisdiction. What happened is regrettable but understandable given the sweeping scope of the FDA’s mission and their limited resources. Should they have inspected the PCA facility? Probably. However, hindsight is 20/20.
Well, if they don't approve drugs fast enough, they are blamed for holding up medical advances; when they DO approve drugs after they've been tested in 4,000 or so patients (or even 2,000) and then after they are on the market 1 in 40,000 has a bad reaction, they are blamed! Sorry, but they cannot win...
