The ACLU is representing several plaintiffs in a recently filed lawsuit challenging the U.S. government’s “No Fly” list. The video in this “Blog of Rights” post tells the story of two of the plaintiffs. “I wanna go home!” laughs U.S. Marine veteran Ayman Latif. “I wanna see my mom. I want her to see my babies.”

No-fly listing is a constitutional aberration in which the executive branch unilaterally imposes a disability on persons it selects using unpublished criteria. It often denies these individuals any recourse by obscuring the reasons why they aren’t permitted to fly. Bills in the House and Senate would extend the use of the “no-fly” list to use in gun control.

There is no way to clear up the “no-fly” status of innocent travelers once and for all. The DHS’ Traveler Redress Inquiry Program may be good for unraveling mistaken name matching, but evidently it hasn’t cured the problem for these travelers.

No-fly listing is also a weak security measure. It’s CYA—“See? We did something!”—but it creates a class of people too dangerous to let fly but not so dangerous that they are sought for arrest.

There is some merit to watch- and no-fly-listing in the international context, where the U.S. is often unable to pursue threatening individuals. But generally, as I wrote in my book, Identity Crisis, “this procedure is like posting a most-wanted list at a post office and then waiting for criminals to come to the post office. It is a singularly lazy way to ‘pursue’ terrorists.”

Another security demerit: No-fly listing gives away the store. It tells any terrorist on a list that he or she is a suspect.

Since 9/11, airports and air travel have been something of a constitution-free zone. Exigency in the first year after that stunning attack may have justified some of the practices begun then, but we are secure and confident enough today to adhere to the Constitution. This lawsuit may vindicate due process values and the important liberty interest in freedom of movement.
