Demonstrators are dubbing Wednesday "National Opt-Out Day," encouraging travelers to refuse the use of the full-body scanners and instead have a full-body pat down, which takes longer. The protesters say the scanners grossly violate a traveler's privacy rights and dignity. The protests come on the day before Thanksgiving, which is traditionally the busiest travel day of the year in the United States. The head of the Transportation Security Administration, John Pistole, told American television ABC's Good Morning America on Wednesday that travelers should expect delays because of the protests. He says his agency is fully staffed and prepared to handle disruptions at airports across the country. The Obama administration says the enhanced security measures are necessary to thwart terror plots like the attempted bombing of a U.S.-bound plane last Christmas by a Nigerian man who put explosives in his underwear. On Thanksgiving, Americans gather with family and friends to give thanks, a tradition started by English settlers nearly 400 years ago. The American automobile agency, AAA, projects that more than 42 million Americans will travel during the Thanksgiving holiday period, lasting from November 24 to November 28. A poll conducted Sunday by the Washington Post and ABC News found that while the majority of people support using the scanners, about half of those surveyed said the pat-downs go too far. The poll also found that those surveyed want the government to focus on investigating possible terrorist attacks, even if that intrudes on personal privacy. White House spokesman Robert Gibbs noted that the new procedures are in place only at 69 out of the nearly 450 airports in the United States.
