I acknowledge that the airline captain has some responsibility for our security. But part of this responsibility is being a steward for our overall well-being. And in this case, the "security" aspect is so vastly overwhelmed by the damage it did to passengers in other ways, that it was obviously a bad call on the captain's part.

It really does break both ways. Over-reacting to perceived threats has a cost too.

Warning - semi-political (but hopefully non-partisan) political content ahead: This is the same thing the FDA does with drug approvals. They are overwhelmingly biased toward preventing bad drugs that they prevent access to a lot of things that could help. Studies show that the FDA's difference between up-side and down-side risk costs a lot of lives on net. For example, the FDA delayed the approval of beta-blockers (used to prevent second heart attacks) for several years after they were widely available and saving lives in Europe. Analysts estimate that this delay alone cost tens of thousands of American lives.

Sometimes, accepting a risk provides the greatest net benefit.
