Mahmoud Khalil, a Columbia graduate and detained student‑protester, sued the federal government seeking records about its use of doxxing sites such as Canary Mission to identify pro‑Palestinian protesters, alleging the administration relied on shadowy lists to target students. Khalil’s lawyers say a Freedom of Information Act request went unanswered, and the lawsuit seeks disclosure about the depth of collaboration between federal agencies and doxxing organizations. The case raises questions about federal surveillance of campus activism, the use of open‑source doxing tools in immigration and enforcement actions, and the boundaries of government investigation into protest activities. Campus legal teams and student‑affairs leaders should expect greater litigation risk around information requests and potential subpoenas tied to protest policing.
