Wall Street sees security winning out over privacy after failed bombing

The failed attempt to bomb a Northwest flight from Amsterdam to Detroit is expected to give momentum to those arguing for high-tech scanning systems that might have detected the explosives the alleged Detroit bomber hid in his underwear.

In June, the House approved an amendment sponsored by Rep. Jason Chaffetz (R-Utah) that would prohibit the Transportation Security Administration from using Whole Body-Imaging machines for primary screening at airports. The amendment was approved in a 310-118 vote, with 191 Democrats and 119 Republicans voting for it. (Both House Majority Leader Steny Hoyer, D-Md., and Minority Leader John Boehner, R-Ohio voted aye.)
