A ProPublica report documents ICE's detention of approximately 170 American citizens during immigration enforcement operations, revealing widespread Fourth Amendment violations. The article details multiple cases of ICE agents using excessive force against U.S. citizens, including pepper-spraying a man filming agents, tackling a 79-year-old car wash owner, and detaining a woman without outside contact for over two days, despite Department of Homeland Security claims that ICE does not arrest U.S. citizens for immigration enforcement.
