"Promoting Public Confidence"
Some call it security theater. Others talk about "promoting public confidence."
From a Scientific American article about an eventual flu pandemic: Screening incoming travelers for flu symptoms, for instance, "lacks proven health benefit," the group concluded, although they acknowledged that countries might do it anyway to promote public confidence. Similarly, they were skeptical that public fever screening, fever hotlines or fever clinics would do much to slow the spread of the disease.
