Heeding a sudden furor, John Pistole, administrator of the Transportation Security Administration, said in a Sunday afternoon statement to POLITICO that airport screening procedures “will be adapted as conditions warrant,” in an effort to make them “as minimally invasive as possible, while still providing the security that the American people want and deserve.” 
  
 TSA's new flexibility comes as the government gears up for a flood of travel over the Thanksgiving holiday weekend. Administration officials say any changes are more likely to be in the implementation of the security procedures than in the security measures themselves.

 Pistole’s statement to POLITICO modified his vow a few hours earlier on CNN’s “State of the Union” that the procedures were "not going to change." Both President Barack Obama and Secretary of State Hillary Clinton said over the weekend that the administration was continually looking for ways to refine the screening to make it less intrusive and frustrating. 
  
 Here is the full text of the statement from Pistole, a former deputy director of the FBI: 
  
 "We welcome feedback and comments on the screening procedures from the traveling public, and we will work to make them as minimally invasive as possible, while still providing the security that the American people want and deserve. We are constantly evaluating and adapting our security measures, and as we have said from the beginning, we are seeking to strike the right balance between privacy and security. 
  
 “In all such security programs, especially those that are applied nationwide, there is a continual process of refinement and adjustment to ensure that best practices are applied and that feedback and comment from the traveling public is taken into account. This has always been viewed as an evolving program that will be adapted as conditions warrant, and we greatly appreciate the cooperation and understanding of the American people. 
  
 “We cannot forget that less than one year ago a suicide bomber with explosives in his underwear tried to bring down a plane over Detroit. The terrorists allegedly behind the thwarted cargo attempt last month are out there bragging about how they will strike again. 
  
 “We all wish we lived in a world where security procedures at airports weren't necessary, but that just isn't the case." ||||| Washington (CNN) -- Enhanced security pat-downs that have been vilified by travelers as legal groping are here to stay, at least for now, the federal official in charge of transportation security told CNN on Sunday. 
  
 John Pistole, the administrator of the Transportation Security Administration, said he understood public discomfort over having a stranger touch the buttocks, breasts and genitals in trying to find possible hidden explosives, but he called the extra screening necessary. 
  
 "We're not changing the policies, because of... the risks that have been identified," Pistole said on CNN's "State of the Union." "We know through intelligence that there are determined people, terrorists who are trying to kill not only Americans but innocent people around the world." 
  
 Travelers who set off metal detectors at airport security are asked to undergo extra screening. If they refuse to go through an enhanced visual device that shows the body through clothing, they are required to submit to the thorough pat-down in order to fly. 
  
 Incidents such as last December's failed bombing of a U.S.-bound flight by a man with explosives in his underwear and the recent detection of explosives in air cargo packages from Yemen prompted the enhanced screening. 
  
 But the more thorough pat-down process has generated alarm and anger, with some travelers complaining they were given little warning of the procedure and that they felt violated by the touching of private parts. 
  
 Critics, including conservative Republicans who generally oppose government regulation, say the enhanced screening is a knee-jerk and excessive reaction. 
  
 "I don't think the roll-out was good and the application is even worse," Rep. John Mica, R-Florida, said Sunday on "State of the Union." "This does need to be refined. But he's saying it's the only tool and I believe that's wrong." 
  
 Democrats also acknowledged the difficulty of the issue. Asked if she would submit to an enhanced pat-down, Secretary of State Hillary Clinton told the CBS program "Face the Nation": "Not if I could avoid it. No, I mean, who would?" 
  
 On the same program, Rep. Steny Hoyer of Maryland, the second-ranking House Democrat, said, "I don't think any of us would want to undergo that," but added that "most people understand that we've got to keep airplanes safe." 
  
 Clinton called for continuing study of the security situation to come up with the proper balance between protecting the public from terrorists and avoiding excessive screening. 
  
 "If there is a way to limit the number of people who are going to be put through surveillance, that's something that I'm sure can be considered," she said. 
  
 Pistole also spoke of seeking a balance between safety and public comfort. 
  
 "I think it is situational, frankly," he said on CNN. "So for you, you may say, 'I want this level of security because I want to know that everybody else on that plane has been screened thoroughly.' Somebody else may say, 'Well, I would rather manage some risk and say I don't want that thorough of screening, so I would rather take a higher risk.' " 
  
 For the TSA, he said, "it comes down to how do we give the highest level of confidence to everybody on that flight that everybody else has been properly screened, including you and me?" 
  
 Pistole noted that few passengers face the enhanced pat-down -- only those who trigger an initial safety alarm in the metal detector or document-screening, and then refuse to go through the advanced visual screening. 
  
 "The advanced imaging technology is designed to detect non-metallics," Pistole said. "So you just have to make sure you take everything out of your pockets. So if there's no alarm, there's no pat-down." 
  
 He also complained of "horror stories" about the enhanced pat-down that he said are "frankly inaccurate, either misinformation or whatever." 
  
 At the same time, Pistole acknowledged that travelers received little warning of the enhanced screening procedures, and therefore those who faced the more thorough pat-down were likely caught by surprise. 
  
 "That's my responsibility, because I did not advertise this, if you will, and say we are going to do this new type of pat-down, because I did not want to provide a blueprint or a road map to the terrorists to say, 'here's our new security procedure, so here's all you have to do to,' " Pistole said. 
  
 Mica and other conservatives call for easing the use of enhanced screening for travelers who clearly pose no security risk. Mica cited Israel's use of passenger profiling based on travel history, age and other factors to determine more likely security risks. 
  
 Pistole, however, said the United States doesn't use the same kind of profiling, and he also noted that travelers who trigger a security question in Israel also undergo a rigorous pat-down. 
  
 "That is top-notch security," Pistole said. "The question is, do we profile here in the U.S.? No, we don't. So how then do we use intelligence that informs the decisions and judgements? And given what we saw from last night in terms of this new Web publication that describes in detail how the cargo bombs were done, how the design concealed, and how they are using technology to disguise and defeat the screening mechanisms we have in place; look, it's a difficult question." |||||

Enhanced pat-down policies are “not changing” due to “the risks that have been identified,” the TSA chief told CNN yesterday—before quickly amending his words in a statement to Politico. Airport security screenings “will be adapted as conditions warrant,” John Pistole wrote, making them “as minimally invasive as possible, while still providing the security that the American people want and deserve.” "We know through intelligence that there are determined people, terrorists who are trying to kill not only Americans but innocent people around the world," he had said earlier on CNN. As for why the more intense pat-downs were sprung on the traveling public without much warning, "I did not want to provide a blueprint or a road map to the terrorists to say, 'Here's our new security procedure, so here's all you have to do.'"
