After Umar Farouk Abdulmutallab’s attempt to blow up a jetliner en route to the US on Christmas Day, American airports plan to triple the number of full body scanners from 40 to 150. The machines have led a debate on where the line should be drawn on security measures to preserve the privacy of citizens.
Analysts call the scans virtual strip searches, as they can see through passenger clothing, creating naked images of passengers. ACLU Washington Legislative Office policy counsel Michael German says they will not detect explosives hidden in body cavities, making them both ineffective, inconvenient, and personally invasive.
Naked images could be shared through the internet, but measures are being taken to prevent this.
They are also expensive. At a cost of $150,000 each, aviation and business experts say there will be a rise in air travel costs in order to pay for the machines. Increasing costs concern not only passengers but also airlines, who have struggled to stay in business.
