US court upholds use of airport body scanners

A US appeals court on Friday upheld the use of full-body scanners to screen air travellers, but said the Transportation Security Administration should have sought public comment before deploying them. The US Court of Appeals for the District of Columbia Circuit ruled that the machines, known as Advanced Imaging Technology (AIT), were not an unconstitutional search and declined to halt their use despite TSA's failure to follow proper procedure.
Privacy advocates, who have strongly opposed the use of the machines, had argued their use constituted an illegal search under the US Constitution's Fourth Amendment. They also said TSA failed to provide public notice that it was deploying them and to seek public comment.
