In an age of international travel — where large numbers of citizens, especially those involved in sensitive journalism and activism, frequently travel outside the country — this power renders the protections of the Fourth Amendment entirely illusory. By virtue of that amendment, if the government wants to search and seize the papers and effects of someone on U.S. soil, it must (with some exceptions) first convince a court that there is probable cause to believe that the objects to be searched relate to criminal activity and a search warrant must be obtained. But now, none of those obstacles — ones at the very heart of the design of the Constitution — hinders the U.S. government: now, they can just wait until you leave the country, and then, at will, search, seize and copy all of your electronic files on your return. That includes your emails, the websites you’ve visited, the online conversations you’ve had, the identities of those with whom you’ve communicated, your cell phone contacts, your credit card receipts, film you’ve taken, drafts of documents you’re writing, and anything else that you store electronically: which, these days, when it comes to privacy, means basically everything of worth.

This government abuse has received some recent attention in the context of WikiLeaks. Over the past couple of years, any American remotely associated with that group — or even those who have advocated on behalf of Bradley Manning — have been detained at the airport and had their laptops, cellphones and cameras seized: sometimes for months, sometimes forever. But this practice usually targets people having nothing to do with WikiLeaks.

A 2011 FOIA request from the ACLU revealed that just in the 18-month period beginning October 1, 2008, more than 6,600 people — roughly half of whom were American citizens — were subjected to electronic device searches at the border by DHS, all without a search warrant. Typifying the target of these invasive searches is Pascal Abidor, a 26-year-old dual French-American citizen and an Islamic Studies Ph.D. student who was traveling from Montreal to New York on an Amtrak train in 2011 when he was stopped at the border, questioned by DHS agents, handcuffed, taken off the train and kept in a holding cell for several hours before being released without charges; those DHS agents seized his laptop and returned it 11 days later when, the ACLU explains, “there was evidence that many of his personal files, including research, photos and chats with his girlfriend, had been searched.” That’s just one case of thousands, all without any oversight, transparency, legal checks, or any demonstration of wrongdoing.

But the case of Laura Poitras, an Oscar-and Emmy-nominated filmmaker and intrepid journalist, is perhaps the most extreme. In 2004 and 2005, Poitras spent many months in Iraq filming a documentary that, as The New York Times put it in its review, “exposed the emotional toll of occupation on Iraqis and American soldiers alike.” The film, “My Country, My Country,” focused on a Sunni physician and 2005 candidate for the Iraqi Congress as he did things like protest the imprisonment of a 9-year-old boy by the U.S. military. At the time Poitras made this film, Iraqi Sunnis formed the core of the anti-American insurgency and she spent substantial time filming and reporting on the epicenter of that resistance. Poitras’ film was released in 2006 and nominated for the 2007 Academy Award for Best Documentary.

In 2010, she produced and directed “The Oath,” which chronicled the lives of two Yemenis caught up in America’s War on Terror: Salim Hamdan, the accused driver of Osama bin Laden whose years-long imprisonment at Guantanamo led to the 2006 Supreme Court case, bearing his name, that declared military commissions to be a violation of domestic and international law; and Hamdan’s brother-in-law, a former bin Laden bodyguard. The film provides incredible insight into the mindset of these two Yemenis. The NYT feature on “The Oath” stated that, along with “My Country, My Country,” Poitras has produced ”two of the most searching documentaries of the post-9/11 era, on-the-ground chronicles that are sensitive to both the political and the human consequences of American foreign policy.” At the 2010 Sundance film festival, “The Oath” won the award for Best Cinematography.

Poitras’ intent all along with these two documentaries was to produce a trilogy of War on Terror films, and she is currently at work on the third installment. As Poitras described it to me, this next film will examine the way in which The War on Terror has been imported onto U.S. soil, with a focus on the U.S. Government’s increasing powers of domestic surveillance, its expanding covert domestic NSA activities (including construction of a massive new NSA facility in Bluffdale, Utah), its attacks on whistleblowers, and the movement to foster government transparency and to safeguard Internet anonymity. In sum, Poitras produces some of the best, bravest and most important filmmaking and journalism of the past decade, often exposing truths that are adverse to U.S. government policy, concerning the most sensitive and consequential matters (a 2004 film she produced for PBS on gentrification of an Ohio town won the Peabody Award and was nominated for an Emmy).

But Poitras’ work has been hampered, and continues to be hampered, by the constant harassment, invasive searches, and intimidation tactics to which she is routinely subjected whenever she re-enters her own country. Since the 2006 release of “My Country, My Country,” Poitras has left and re-entered the U.S. roughly 40 times. Virtually every time during that six-year-period that she has returned to the U.S., her plane has been met by DHS agents who stand at the airplane door or tarmac and inspect the passports of every de-planing passenger until they find her (on the handful of occasions where they did not meet her at the plane, agents were called when she arrived at immigration). Each time, they detain her, and then interrogate her at length about where she went and with whom she met or spoke. They have exhibited a particular interest in finding out for whom she works.

She has had her laptop, camera and cellphone seized, and not returned for weeks, with the contents presumably copied. On several occasions, her reporter’s notebooks were seized and their contents copied, even as she objected that doing so would invade her journalist-source relationship. Her credit cards and receipts have been copied on numerous occasions. In many instances, DHS agents also detain and interrogate her in the foreign airport before her return, on one trip telling her that she would be barred from boarding her flight back home, only to let her board at the last minute. When she arrived at JFK Airport on Thanksgiving weekend of 2010, she was told by one DHS agent — after she asserted her privileges as a journalist to refuse to answer questions about the individuals with whom she met on her trip — that he “finds it very suspicious that you’re not willing to help your country by answering our questions.” They sometimes keep her detained for three to four hours (all while telling her that she will be released more quickly if she answers all their questions and consents to full searches).

Poitras is now forced to take extreme steps — ones that hamper her ability to do her work — to ensure that she can engage in her journalism and produce her films without the U.S. Government intruding into everything she is doing. She now avoids traveling with any electronic devices. She uses alternative methods to deliver the most sensitive parts of her work — raw film and interview notes — to secure locations. She spends substantial time and resources protecting her computers with encryption and password defenses. Especially when she is in the U.S., she avoids talking on the phone about her work, particularly to sources. And she simply will not edit her films at her home out of fear — obviously well-grounded — that government agents will attempt to search and seize the raw footage.

That’s the climate of fear created by the U.S. Government for an incredibly accomplished journalist and filmmaker who has never been accused, let alone convicted, of any wrongdoing whatsoever. Indeed, documents obtained from a FOIA request show that DHS has repeatedly concluded that nothing incriminating was found from its border searches and interrogations of Poitras. Nonetheless, these abuses not only continue, but escalate, after six years of constant harassment.

Poitras has been somewhat reluctant to speak publicly about the treatment to which she is subjected for fear that doing so would further impede her ability to do her work (the NYT feature on “The Oath” included some discussion of it). But the latest episode, among the most aggressive yet, has caused her to want to vociferously object.

On Thursday night, Poitras arrived at Newark International Airport from Britain. Prior to issuing her a boarding pass in London, the ticket agent called a Customs and Border Patrol (CBP) agent (Yost) who questioned her about whom she met and what she did. Upon arriving in Newark, DHS/CBP agents, as always, met her plane, detained her, and took her to an interrogation room. Each time this has happened in the past, Poitras has taken notes during the entire process: in order to chronicle what is being done to her, document the journalistic privileges she asserts and her express lack of consent, obtain the names of the agents involved, and just generally to cling to some level of agency.

This time, however, she was told by multiple CBP agents that she was prohibited from taking notes on the ground that her pen could be used as a weapon. After she advised them that she was a journalist and that her lawyer had advised her to keep notes of her interrogations, one of them, CBP agent Wassum, threatened to handcuff her if she did not immediately stop taking notes. A CBP Deputy Chief (Lopez) also told her she was barred from taking notes, and then accused her of “refusing to cooperate with an investigation” if she continued to refuse to answer their questions (he later clarified that there was no “investigation” per se, but only a “questioning”). Requests for comment from the CBP were not returned as of the time of publication.

Just consider the cumulative effect of this six years of harrassment and invasion. Poitras told me that it is “very traumatizing to come home to your own country and have to go through this every time,”and described the detentions, interrogations and threats as “infuriating,” “horrible” and “intimidating.” She told me that she now “hates to travel” and avoids international travel unless it is absolutely necessary for her work. And as she pointed out, she is generally more protected than most people subjected to similar treatment by virtue of the fact that she is a known journalist with both knowledge of her rights and the ability to publicize what is done to her. Most others are far less able to resist these sorts of abuses. But even for someone in Poitras’ position, this continuous unchecked government invasion is chilling in both senses of the word: it’s intimidating in its own right, and deters journalists and others from challenging government conduct.

As is true for so many abuses of the Surveillance State and assaults on basic liberties in the post-9/11 era, federal courts have almost completely abdicated their responsibility to serve as a check on these transgressions. Instead, federal judges have repeatedly endorsed the notion that the U.S. Government can engage in the most invasive border searches of citizens, including seizures and copying of laptops, without any reasonable suspicion of wrongdoing whatsoever, let alone probable cause.

That has happened in part because federal courts have become extremely submissive to assertions of Executive authority in the post-9/11 era, particularly when justified in the name of security. It’s also in part because anyone with a record of anti-authoritarianism or a willingness to oppose unrestrained government power, with very rare exception, can no longer get appointed to the federal bench; instead, it’s an increasingly homogeneous lot with demonstrated fealty to institutional authority. And it’s also in part because many life-tenured federal judges have been cloistered on the bench for decades, are technologically illiterate, and thus cannot apprehend the basic difference between having your suitcase searched at the airport and having the contents of your laptop and cellphone copied and stored by the U.S. Government.

One potentially important and encouraging exception to this trend was a ruling two weeks ago by U.S. District Judge Denise Casper, an Obama-appointed judge in the District of Massachusetts. As I’ve reported previously, David House, an activist who helped found the Bradley Manning Support Network, was detained by DHS when returning from a vacation in Mexico and had all of his electronic devices, including his laptop, seized; those devices were returned to him after almost two months only after he retained the ACLU of Massachusetts to demand their return. The ACLU then represented him in a lawsuit he commenced against the U.S. Government, alleging that his First and Fourth Amendment rights were violated by virtue of being targeted for his political speech and advocacy.

The DOJ demanded dismissal of the lawsuit, citing the cases approving of its power to search without suspicion, and also claimed that House was targeted not because of his political views but because of his connection to the criminal investigation of Manning and WikiLeaks. But the court refused to dismiss House’s lawsuit, holding that if he were indeed targeted by virtue of his protected activities, then his Constitutional rights have been violated:

Before even questioning House, the agents seized his electronic devices and in seizing them for forty-nine days, reviewed, retained, copied and disseminated information about the Support Network. Although the agents may not need to have any particularized suspicion for the initial search and seizure at the border for the purpose of the Fourth Amendment analysis, it does not necessarily follow that the agents, as is alleged in the complaint, may seize personal electronic devices containing expressive materials, target someone for their political association and seize his electronic devices and review the information pertinent to that association and its members and supporters simply because the initial search occurred at the border. . . .

When agents Santiago and Louck stopped House while he was en route to his connecting flight, they directed him to surrender the electronic devices he was carrying. They questioned him for an extended period of time only after seizing his devices. When the agents questioned House, they did not ask him any questions related to border control, customs, trade, immigration, or terrorism and did not suggest that House had broken the law or that his computer may contain illegal material or contraband. Rather, their questions focused solely on his association with Manning, his work for the Support Network, whether he had any connections to WikiLeaks, and whether he had contact with anyone from WikiLeaks during his trip to Mexico. Thus, the complaint alleges that House was not randomly stopped at the border; it alleges that he was stopped and questioned solely to examine the contents of his laptop that contained expressive material and investigate his association with the Support Network and Manning. . . .

That the initial search and seizure occurred at the border does not strip House of his First Amendment rights, particularly given the allegations in the complaint that he was targeted specifically because of his association with the Support Network and the search of his laptop resulted in the disclosure of the organizations, members, supporters donors as well as internal organization communications that House alleges will deter further participation in and support of the organization. Accordingly, the Defendants’ motion to dismiss House’s First Amendment claim is DENIED. [emphasis added]

As Kevin Gosztola notes in an excellent report on this ruling, the court — although it dubiously found that “the search of House’s laptop and electronic devices is more akin to the search of a suitcase and other closed containers holding personal information travelers carry with them when they cross the border which may be routinely inspected by customs and require no particularized suspicion” – also ruled that the length of time DHS retained House’s laptop (six weeks) may render the search and seizure unreasonable in violation of the Fourth Amendment.

But thus far, very few efforts have been made to restrain this growing government power. More than a year ago, Democratic Rep. Loretta Sanchez described to me legislation she proposed just to impose some minimal rules and safeguards governing what DHS can do at the airport, but it’s gone nowhere. A much stronger bill, proposed by then-Sen. Feingold, would have barred laptop seizures entirely without a search warrant, but it suffered the same fate. Apparently, the Small Government faction calling itself the “Tea Party” has no greater interest in restraining this incredibly invasive government power than the Democratic Party which loves to boast of its commitment to individual rights.

It’s hard to overstate how oppressive it is for the U.S. Government to be able to target journalists, film-makers and activists and, without a shred of suspicion of wrongdoing, learn the most private and intimate details about them and their work: with whom they’re communicating, what is being said, what they’re reading. That’s a radical power for a government to assert in general. When it starts being applied not randomly, but to people engaged in activism and journalism adverse to the government, it becomes worse than radical: it’s the power of intimidation and deterrence against those who would challenge government conduct in any way. The ongoing, and escalating, treatment of Laura Poitras is a testament to how severe that abuse is.

If you’re not somebody who films the devastation wrought by the U.S. on the countries it attacks, or provides insight into Iraqi occupation opponents and bin Laden loyalists in Yemen, or documents expanding NSA activities on U.S. soil, then perhaps you’re unlikely to be subjected to such abuses and therefore perhaps unlikely to care much. As is true for all states that expand and abuse their own powers, that’s what the U.S. Government counts on: that it is sending the message that none of this will affect you as long as you avoid posing any meaningful challenges to what they do. In other words: you can avoid being targeted if you passively acquiesce to what they do and refrain from interfering in it. That’s precisely what makes it so pernicious, and why it’s so imperative to find a way to rein it in.
