Full-body imaging might have detected that Umar Farouk Abdulmutallab had stuffed his underwear with explosives before he boarded a Detroit-bound flight on Christmas day.

But a considerable bipartisan majority of U.S. House members are on record opposing the widespread use of such scans in a vote that saw privacy concerns trump security measures. In June, the House voted 310-to-118 for an amendment by Rep. Jason Chaffetz, R-Utah, that would have prohibited whole-body imaging as a “primary screening” method at airports. The amendment died in the Senate.

Chaffetz’s amendment would have allowed such scans as a “secondary” screening method, but passengers would be given the option of a pat-down search in lieu of whole-body imaging and the Transportation Security Administration would have been banned from “storing, transferring, or copying any images” from the scans.

Local U.S. Reps. Alcee Hastings, D-Miramar; Tom Rooney, R-Tequesta; and Robert Wexler, D-Boca Raton, supported the ban on whole-body imaging. U.S. Rep. Ron Klein, D-Boca Raton, voted against the Chaffetz amendment.
