Via Reuters:  U.S. security rethinking airline screening:

"We’re going to look at how can we do the most effective screening in the least invasive way knowing that there’s always a trade-off between security and privacy," Transportation Security Administrator John Pistole told NBC’s "Today" show.

"What I’m doing is going back and looking at, are there less invasive ways of doing the same type of screening?" he said on ABC’s "Good Morning America."

Coming amid public and political pressure, Pistole’s comments appeared to row back from a Sunday interview in which he said there were no plans to scale back procedures that travelers have criticized as invasive and a violation of privacy rights.
