Everyone makes mistakes...

...but when governments do so, the costs/consequences are enormous:

Two months ago, we pointed out in our story on flu in The Atlantic that the antiviral drug Tamiflu might not be as effective or safe as many patients, doctors, and governments think. The drug has been widely prescribed since the first cases of H1N1 flu surfaced last spring, and the U.S. government has spent more than $1.5 billion stockpiling it since 2005 as part of the nation’s pandemic preparedness plan.

Now it looks as if our concerns were correct, and the nation may have put more than a billion dollars into the medical equivalent of a mirage.
