Pistole says no change in airport screening policy
Washington - The head of the Transportation Security Administration says that while new airport screening procedures are more invasive, threats against air travelers rule out policy changes.
John Pistole tells CNN's "State of the Union" that the agency has no plans to change its policy of requiring travelers at many major airports to undergo either enhanced body scans or thorough pat-downs.
Pistole says screeners are "really the last line of defense" in the effort to keep the traveling public safe against a "determined enemy" that has proved adept in coming up with new ways to conceal explosive devices.
He says he understands the objections of some passengers.
