Does terrorism risk permit open-ended detention?

An article in the New York Times describes a lawsuit filed by Nicole Hallett and Jonathan Manes, both assistant clinical professors of law, on behalf of Adham Hassoun, a Palestinian computer programmer and former Florida resident who served a 15-year U.S. prison sentence for sending support to Islamist militants abroad and has since been deemed him a security risk by the Trump administration. The lawsuit is the latest chapter in a series of disputes over when the government may label people terrorism risks to hold them in open-ended detention, and what due-process rights they have to contest their indefinite lockup.
