As Rep. Jason Chaffetz plans to introduce legislation next week limiting airport security's use of body imaging scanners he considers intrusive, Salt Lake airline passengers seem largely indifferent to the new technology.

"They can scan me down to the DNA level if it gets me on an airplane faster," said Jude Lancaster of Chicago as he filed through the security line at the Salt Lake International Airport on Friday.

Salt Lake is one of six cities where the Transportation Security Administration is testing the whole body imaging technology as a primary screening. The new technique provides security screeners with an X-ray-like image of passengers' bodies to show if the individual has weapons, explosives or other prohibited items concealed under their clothes.

"I don't have any problems with it," said Matt Sumsion of Bountiful. "It's just a body."

Chaffetz , who this week called the images "TSA porn" and said the scans "go too far," met with TSA officials Thursday evening for a demonstration of the system at the Salt Lake airport and explanation of the airport's policies.

But the freshman Republican congressman said he still considers the screening technique an invasion of privacy and plans to introduce legislation Wednesday to restrict the use of the scanners. It would be Chaffetz's first bill introduced since he took office in January.

"I think it's intrusive, too," said Dewayne Butcher of Milwaukee. "Gees. I don't think they should [do this]. There are other ways they should be able to do it."

But most of those interviewed at the Salt Lake airport on Friday weren't concerned about the procedure.

TSA spokesman Nico Melendez said there "seems to be a misperception" about the use of the body imaging. He emphasized that the program is still in a pilot phase to determine if it's a practical, effective technology.

"Until we have good data to go with, a decision won't be reached until that time," he said. "I think it's important for us to be able to get data for the technology to be sure it's an effective alternative."

But Chaffetz disagrees, and says the TSA is moving in the direction of making the imaging mandatory.

"They don't believe it's there for primary screening and I think there's a little bit of a dispute about that, because it is being used for primary screening in Salt Lake. I've seen it," said Chaffetz. "That's why I feel compelled to move on it."

At the Salt Lake airport, randomly selected passengers step into a glass chamber and raise their arms over their heads for the scan. The images are reviewed at a separate location, so the official screening the images doesn't see the individual. None of the images is stored or printed.

A sign outside the machine tells passengers they can refuse to go through the scanner and be subjected to a pat-down instead.

Melendez said that about 50,000 people have gone through the scanner in Salt Lake and only about 100 refused. The rate is similar in other cities where the program is being tested.

"If it's going to prevent things with terrorists, then I think it's OK," said Melody Van Deventer, who is from England.

"I feel like that is a little much, but I guess a body is a body," said Briana Millett of Salt Lake.
