Adam Marshall, a former infantry officer who has volunteered for over a year helping families of detainees, was arrested and briefly detained while serving as a medic for protesters who had been pepper-sprayed outside Delaney Hall in May 2026. Federal agents pushed him to the ground, carried him by his arms and legs into the detention center's courtyard, scanned his face with a mobile application, held him for two hours, then transported him and two other men to an underpass beneath the New Jersey Turnpike where they were lined up against a metal wall with hands above their heads before being told never to return and released.
