DETROIT — An airline-security expert said Friday that one thing is clear: The incident in Detroit should prompt a swift re-evaluation of passenger screening at airports throughout the world.

Douglas Laird, former security director for Northwest Airlines, said he has been advocating for years that airports switch from X-rays and metal detectors to full-body scans, a move that would cost hundreds of millions of dollars more, but that he insists would help prevent terrorist attempts like the one reported Friday.
