The Transportation Security Administration has a new rule for airport screenings.

TSA screeners can now force anyone to submit to a body-scan, even if that person wants to opt out.

Previously, passengers could request a full body pat down instead.

The TSA says the scanner does not store personal information and improves threat detection.

Specifically, the TSA says the scanners help detect metallic and non-metallic objects that might be missed during a pat-down.
