John Pistole, head of the Transportation Security Administration, says the inconvenience of body scanners and pat downs is a small price to pay for safety.
The debate over expanded screening touches on the proper balance between safety and civil liberties. Some legal experts wonder whether the TSA violates the Fourth Amendment protection against unreasonable search and seizure. Mr. Pistole is bracing for a grilling on Capitol Hill and likely legal challenges.

The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
