Earlier quoted context omitted.
A problem with bureaucracies is that they often care deeply if people die from an action they are responsible for, but are fine if there are massive deaths due to inaction.
The solution is simple though: politicians simply ask experts how many people die if they do X versus Y, and make sure it is recorded (e.g. by journalists) so they can refer to it later.
The best strategy (however cynical) is to not be quantitatively explicit about expectations so that you can frame it as though you succeeded no matter what happens.
