Heartland Alliance’s National Immigrant Justice Center (sometimes referred to as Heartland Alliance National Immigration Justice Center—we’ll just call it the Center) is, we read on its website, www.immigrantjustice.org/about-nijc (visited October 19, 2016), “dedicated to ensuring human rights protections and access to justice for all immigrants, refugees and asylum seekers. [The Center] provides direct legal services to and advocates for these populations through policy reform, impact litigation, and public education. Since its founding three decades ago, [the Center] has been unique in blending individual client advocacy with' broad-based systemic change.” In the fall of 2011 the Center submitted to the Department of Homeland Security (and to other fedéral agencies as well, but we can ignore them) a request under the Freedom of Information Act, 5 U.S.C. § 562, for information relating to Tier III terrorist organizations, defined by the Immigration and Nationality Act in 8 U.S.C. § 1182(a)(3)(B)(vi)(III). The Department provided only some of the information requested by the Center, so the Center brought this suit to enjoin the Department from withholding the other information that the Center had sought— the names of what are referred to as “Tier III terrorist organizations.” Membership in any of the tiers makes one inadmissible to the United States, with narrow exceptions.
Tier I and Tier II organizations are publicly identified terrorist groups such as ISIS and al-Qaeda. Tier III organizations are defined in 8 U.S.C. § 1182(a)(3)(B)(vi)(III) as any group of two or more people that engages in terrorist activity (as defined in 8 U.S.C. § 1182(a)(3)(B)(iv)), even if their terrorist activity is conducted exclusively against regimes that are enemies of the United States. Tier III organizations tend to have a lower profile than Tier I’s or Tier II’s, not only because the government does not publish them names but also because they tend to be groups about which the U.S. government does not have good intelligence, making it essential that the Department be able to obtain information about them during screening interviews that are as focused and complete as possible. The district judge granted summary judgment for the Department on the ground that the names of the Tier III organizations are protected from disclosure under the Freedom of Information Act by the Act’s 7(E) Exemption, 5 U.S.C. § 552(b)(7)(E). The judge then dismissed Heartland’s suit with prejudice, precipitating this appeal.
The exemption embraces “records or information compiled for law enforcement purposes, but only to the extent that the production of such law enforcement records or information ... would disclose techniques and procedures for law enforcement investigations or prosecutions, or would disclose guidelines for law enforcement investigations or prosecutions if such disclosure could reasonably be expected to risk circumvention of the law.” The Center contends not without reason that names of organizations are not “guidelines.” We are puzzled by the amount of space in its brief the government devotes to trying to show that they are “guidelines.” Our puzzlement *421derives from our inability to see what difference it makes whether the names are or are not guidelines given that the heart of the exemption, at least so far as relates to this case, lies in its authorizing the government not to “disclose techniques and procedures for law enforcement investigations or prosecutions.”
The government’s unwillingness to turn over the names of Tier III organizations to the Center—which remember intends to publicize them if it gets its hands on them—rests on a combination of two concerns, both encompassed by the passage in the exemption that we just quoted. The first concern is implicit in the statutory definition of a Tier III organization—“a group of two or more individuals ... which engages in” specified terrorist activities that involve acts of violence, 8 U.S.C. § 1182(a)(3)(B)(vi)(III), making it more likely than in the case of other asylum seekers that if admitted to the United States they would commit violent or otherwise unlawful acts. Second, as explained in the government’s brief, “an alien who becomes aware that a particular organization has been found to fall within the definition of a Tier III organization will have a very strong incentive to falsify or misrepresent any and all encounters, activities, or associations that he or she may have had with that organization.” If the alien doesn’t know that a terrorist organization that he has belonged to, been affiliated with, or maybe simply has provided supplies or money to, has been identified by our government as a terrorist organization, he is likely to be less guarded in answering questions about his activities in or associations with the organization. But if he knows that the organization he belonged to or was associated with is deemed a terrorist organization, he is likely to deny having ever had any connection to it or even having ever heard of it. And if his denials are believed he may—even if he is a past and prospective future terrorist—not only escape the government’s net but also cost the government an opportunity to obtain information about the organization that might in the future help in identifying terrorists. The withholding of the name of a terrorist organization from an alien who is being questioned is thus a technique of a law enforcement investigation that is squarely within the 7(E) exemption.
The Center argues that “no knowing terror affiliate will disclose his or her terror affiliation,” and so the government will learn nothing less from its questioning of aliens if the names were publicized. Well obviously an alien seeking asylum in the United States is not going to tell the government, in response to the question whether he has ever belonged to a terrorist organization, that he did, and it was called [whatever]. But. that would be dumb interrogation. He’ll be asked what he knows about terrorist activities in whatever region he’s from, and in an effort to demonstrate cooperation he may offer information about some terrorist groups— and one of them may be one he has had dealings with. If the government is required to name all terrorist groups at the Tier III level this type of questioning will be ineffectual.
We learn in the Center’s reply brief that its primary concern is not with names but with the Tier III category itself, for it says for example that “the designation of Tier III organizations is often doubtful.” It hopes that if it can obtain the names of all the organizations—its goal in this litigation—it will be able to discredit some or perhaps many of them. Deeply distrustful of the U.S. government, by the tone and content of its briefs the Center signals its disbelief that the government has secrets worth keeping from' asylum seekers and their helpers (such as the Center), but it does not explain what the government *422would gain by pretending that harmless organizations are actually terrorist groups. The government makes mistakes, but the Center has not shown that they’re willful, or that Exemption 7(E), on which this litigation pivots, is either invalid—in fact the Center concedes that the exemption is valid—or inapplicable to the ■ withheld names.
The judgment of the district court is
AFFIRMED.
