According to USA Today, most Americans support the federal government's move to place body scanners in the nation's airports. I'm always skeptical of polls since polling is a very inexact science and depends on the phrasing of the questions. Perhaps the results would have been different if the poll had asked these questions:The government cannot protect you. It is not interested in protecting you. Schemes like body scanners are not designed to make you safer. They are designed to make you feel safer and to convince you that the government is doing something.
