New Documents Show This TSA Program Blamed for Profiling Is Unscientific and Unreliable 鈥� But Still It Continues
Yawning. Whistling. Being distracted. Arriving late for a flight.
Are people who do these things at the airport showing signs of deception? The Transportation Security Administration apparently thinks so. Thousands of TSA officers use so-called 鈥渂ehavior detection鈥� techniques to scrutinize travelers for these and that the TSA calls signs of deception or 鈥渕al-intent.鈥� The officers then flag certain people for additional screening and questioning.
But documents the 老澳门开奖结果 has obtained through a Freedom of Information Act lawsuit show that the TSA itself has plenty of material showing that such techniques are not grounded in valid science 鈥� and they create an unacceptable risk of racial and religious profiling. Indeed, TSA officers themselves that the program has been used to do just that.
We got more than 13,000 pages of documents from the TSA, and today we鈥檙e releasing a on what we found. In the past, , members of Congress from , and have labeled the program wasteful and ineffective. Our study reinforces these conclusions, and more.
Here are the top five things we learned from the TSA鈥檚 documents:
1. Studies in the TSA鈥檚 own files reinforce that the TSA鈥檚 use of behavior detection is unscientific and unreliable.
The TSA turned over numerous academic and scientific research studies. Instead of supporting the program, the literature directly undercuts the notion that officers can detect deceit or bad intentions based on people鈥檚 behavior with any reliability, especially in a place like the airport.
The social science literature in the TSA鈥檚 files even includes specific findings that behaviors people commonly associate with lying 鈥� gaze aversion, nervous or fidgety gestures, or placement of hands over the mouth 鈥� are not reliable cues to deception. But the TSA鈥檚 secret list of indicators includes those very behaviors, along with others for which there is no empirical support.
These documents suggest that the TSA has persisted in maintaining a behavior detection program that is at odds with the scientific studies in its own files.
2. The TSA broadened the behavior detection program and its surveillance techniques.
In 2009, the TSA expanded the program beyond security checkpoints at airports, enabling 鈥渂ehavior detection officers鈥� 鈥� some of them in plain clothes 鈥� to 鈥渟pread throughout the entire airport鈥� and surveil travelers covertly. Officers use 鈥�casual conversation鈥� to draw out information from passengers 鈥� a technique that appears less like conversation and more like stealth interrogation.
These techniques are troubling because travelers likely will assume that they may not simply ignore officers who converse with them. And various behavioral 鈥渋ndicators鈥� (revealed in documents leaked to in 2015) 鈥斺�済ives non-answers,鈥� 鈥渓acking details about purpose of trip,鈥� 鈥渄ownplaying of significant facts when answering questions鈥� 鈥� show how avoiding contact with behavior detection officers can be construed as an indicator itself.

3. The TSA overstated the scientific validity of behavior detection techniques in communications with Congress.
TSA officials have repeatedly assured members of Congress that the behavior detection program uses 鈥�objective criteria鈥� and is 鈥渟upported by leading experts in the field of behavioral science and law enforcement.鈥� Those statements, however, ignored or misconstrued the body of empirical research in the TSA鈥檚 files (or otherwise publicly available) that indicated otherwise.
4. Materials in the TSA鈥檚 possession raise questions about possible anti-Muslim bias at the TSA.
Various documents from the TSA鈥檚 files reflect a disproportionate focus on or an overt bias against Arabs, Muslims, and people of Middle Eastern or South Asian descent. For instance, until late 2012, training materials for behavior detection officers focused exclusively on examples of Arab or Muslim terrorists, and a TSA-authored presentation titled 鈥淔emme Fatale: Female Suicide Bombers鈥� reflects demeaning stereotypes about Muslims and women, including these images:
It is unclear whether and how these materials factored into the TSA鈥檚 behavior detection program, but they do not provide empirical or scientific support for behavior detection methods, and their existence in the TSA鈥檚 records raises concerns about potential bias in TSA programs.
5. The TSA鈥檚 documents reveal details of specific instances of racial or religious profiling.
The TSA produced records of investigations into alleged profiling by behavior detection officers in Newark, Chicago, Miami, and Honolulu. Those records highlight the ease with which behavioral indicators can be used as a pretext for harassing minorities and disfavored groups. They also show that some officers refer passengers for additional screening far more often than others 鈥� a troubling indication that the TSA鈥檚 鈥渋ndicators鈥� are subjective and arbitrary.
Based on the documents, our report includes several recommendations: First, the TSA should phase out the behavior detection program. The available information shows that the program lacks scientific support and threatens civil liberties.
The agency should also implement a rigorous anti-discrimination training program for all TSA employees.
Congress should use its oversight role to make sure that these changes happen. Given the anti-Muslim policies coming from the Trump administration, the TSA should not be allowed to retain a program that can be used as a cover for racial and religious profiling.

老澳门开奖结果 and Partners Urge Supreme Court to Block TikTok Ban老澳门开奖结果 and Partners Urge Supreme Court to Block TikTok Ban
WASHINGTON 鈥� Today, the 老澳门开奖结果, the Electronic Frontier Foundation (EFF), and the Knight First Amendment Institute at Columbia University filed an amicus brief urging the Supreme Court to block the enforcement of a law that would effectively ban people in America from using TikTok as soon as January 19, 2025. Earlier this month, the U.S. Court of Appeals for the D.C. Circuit rejected TikTok鈥檚 challenge to the law. TikTok has asked the Supreme Court for a temporary injunction to prevent the app from being banned while the court considers whether to take the case, saying that unless the justices intervene, the law will 鈥渟hutter one of America鈥檚 most popular speech platforms the day before a presidential inauguration.鈥� 鈥淭he Constitution imposes an extraordinarily high bar on this kind of mass censorship,鈥漵aid Patrick Toomey, deputy director of 老澳门开奖结果鈥檚 National Security Project. 鈥淭he Supreme Court should take up this important case and protect the rights of millions of Americans to freely express themselves and engage with others around the world.鈥� The brief argues that the D.C. Circuit failed to fully address the law鈥檚 profound implications for the First Amendment rights of the 170 million Americans who use TikTok. While the lower court鈥檚 decision correctly recognized that the statute triggers First Amendment scrutiny, it barely addressed users鈥� First Amendment interests in speaking, sharing, and receiving information on the platform. The court also perplexingly attempted to cast the government鈥檚 ban on TikTok as a vindication of users鈥� First Amendment rights, which it is not. The rights groups also explain that the law was intended to suppress certain content and viewpoints that many legislators believe could be amplified on TikTok, including the risk of foreign 鈥減ropaganda.鈥� But under the First Amendment, the government must meet a very high bar to restrict speech based on concerns about its 鈥渕otivating ideology鈥� or 鈥減erspective,鈥� and the government has not come close to meeting that bar here. 鈥淭he government should not be able to restrict speech, especially to the extent here, based on guessing about the mere possibility of uncertain future harm,鈥� said David Greene, civil liberties director at EFF. 鈥淭he Supreme Court should put the TikTok ban on hold while it considers the DC Circuit鈥檚 erroneous ruling.鈥� Finally, the brief underscores that the government can鈥檛 impose this type of sweeping ban unless it鈥檚 necessary to prevent extremely serious and imminent harm to national security. But the government has not provided evidence of impending harm, or evidence that banning TikTok is the only available way to address its concerns. As the brief explains, the D.C. Circuit improperly treated the government鈥檚 invocation of 鈥渘ational security鈥� as a trump card and failed to hold the government to its burden. 鈥淩estricting citizens鈥� access to foreign media is a practice that has long been associated with repressive regimes, and we should be very wary of letting the practice take root here,鈥� said Jameel Jaffer, executive director at the Knight First Amendment Institute at Columbia University. 鈥淚t would do lasting damage to the First Amendment and our democracy if the Supreme Court let this ban go into effect even temporarily.鈥� You can find the brief online here: https://www.supremecourt.gov/DocketPDF/24/24A587/335380/20241217144322392_24A587%20TikTok%20v%20Garland%20Amicus%20Brief%20pdfa.pdf -

老澳门开奖结果 Statement on New White House Strategy to Counter Islamophobia老澳门开奖结果 Statement on New White House Strategy to Counter Islamophobia
WASHINGTON 鈥� The Biden administration today released the first-ever national strategy to counter Islamophobia and related forms of bias and discrimination, including hate against Arab, Sikh, and South Asian Americans. In advance of the strategy, 老澳门开奖结果 and its partners had urged the administration to overhaul government programs that reflect anti-Muslim discrimination. In particular, we have called for urgent action to constrain governmental agencies from continuing to exercise their authorities and technology to wrongly surveil and investigate, watchlist, and question and detain Muslims at the border, as well as deny immigration benefits to people from Muslim-majority countries. While the White House raised expectations that many of these issues would be addressed, the final strategy ended up falling far short. The following is a statement from Hina Shamsi, director of the 老澳门开奖结果鈥檚 National Security Project: 鈥淲hile this strategy acknowledges discrimination and its harms, it does little to end them and is a squandered opportunity. For decades, American officials have invoked national security to pass laws and implement programs that disproportionately harm Muslims and people perceived to be Muslim. A serious anti-discrimination strategy would concretely address multiple bias-infused government practices that deny our communities equal participation in civic life and our democracy, like federal watchlisting, surveillance, and investigation. We鈥檙e profoundly frustrated that the administration didn鈥檛 take even the basic, overdue step of recognizing that anti-Muslim discrimination is uniquely normalized and embedded in government policies.鈥� -

Trabelsi v. Crawford, et al. 鈥� Lawsuit Challenging Unlawful Detention and Inhumane Treatment of Acquitted ManTrabelsi v. Crawford, et al. 鈥� Lawsuit Challenging Unlawful Detention and Inhumane Treatment of Acquitted Man
Our client, Nizar Trabelsi, is in the United States against his will. The federal government brought him here from Belgium more than a decade ago and charged him with terrorism-related crimes. At trial, the government鈥檚 case failed: a federal jury found Mr. Trabelsi not guilty. But instead of allowing Mr. Trabelsi to return to Belgium after his acquittal, the United States placed him in highly restrictive immigration detention and began an ongoing effort to force him to Tunisia, where he was born and where he will very likely be tortured. Mr. Trabelsi鈥檚 detention violates the Constitution, immigration law, and the extradition treaty between the United States and Belgium. Through this lawsuit, he seeks to return to Belgium, and he demands an immediate improvement of his detention conditions. -

Federal Judge Rejects Acquitted Man鈥檚 Argument That His Immigration Detention Is UnlawfulFederal Judge Rejects Acquitted Man鈥檚 Argument That His Immigration Detention Is Unlawful
ALEXANDRIA, Va. 鈥� This week, the U.S. District Court for the Eastern District of Virginia ruled that the court does not have jurisdiction to decide whether the government can continue to detain Nizar Trabelsi, a Tunisian national who was brought to the United States against his will for prosecution and was cleared of all charges last year. The ruling means the United States will be able to continue to detain Mr. Trabelsi while it attempts to deport him to Tunisia, where he was born and where, as an immigration judge ruled earlier this year, he will likely face torture. The court also concluded that even if it did have jurisdiction over Mr. Trabelsi鈥檚 case, his claims challenging the government鈥檚 detention of him would fail. 鈥淩eviewing claims that the government is holding someone unlawfully is at the core of the judicial function, and we鈥檙e heartbroken for our client that the court got this so wrong,鈥� said Brett Max Kaufman, senior staff attorney with the 老澳门开奖结果鈥檚 Center for Democracy. 鈥淭he government鈥檚 arguments in defense of Mr. Trabelsi鈥檚 detention makes a hash of the Constitution, immigration laws, and its own extradition treaty.鈥� In 2013, the United States forcibly extradited Mr. Trabelsi from Belgium to face criminal charges in the United States. In July 2023, after almost 10 years of highly restrictive pretrial detention, a federal jury cleared Mr. Trabelsi of all charges. But instead of releasing Mr. Trabelsi or returning him to Belgium, the U.S. transferred him to immigration detention, wrongly treating him as an applicant for admission and placing him in the deportation process. Over the years, the Belgian government has issued multiple formal diplomatic requests asking the U.S. to facilitate his return, but the U.S. has refused to send him back. Mr. Trabelsi filed a lawsuit challenging the government's authority to detain him. He also sought immediate improvements to his detention conditions. Those claims were not part of the court鈥檚 ruling today, and will continue to be litigated on a separate track. 鈥淢r. Trabelsi only wants to return to Belgium after being illegally extradited to the United States, held for ten years, and then acquitted by a jury of any crimes,鈥� said Nicole Hallett, clinical professor of law and director of the Immigrants鈥� Rights Clinic at the University of Chicago Law School. 鈥淗e cannot be held indefinitely and we will continue to fight to make sure that justice ultimately prevails.鈥� Mr. Trabelsi is represented by the 老澳门开奖结果, the University of Chicago Law School鈥檚 Immigrants鈥� Rights Clinic, the 老澳门开奖结果 of Virginia, and Professor Jonathan Hafetz of Seton Hall Law School. The complaint in Trabelsi v. Crawford was filed against Jeffrey Crawford, warden of the Farmville Detention Center where Mr. Trabelsi is being held; Liana Castano, ICE field office director for the Washington Field Office; Alejandro Mayorkas, secretary of the Department of Homeland Security; and Merrick Garland, U.S. attorney general.
