A new documentary from our sister channel France Télévisions explores US President Donald Trump's relentless crackdown on immigration and the agency carrying it out – United States Immigration and Customs Enforcement, better known as ICE. "ICE : La chasse a l'homme", or "A Manhunt Named ICE" interviews agents and also some of the people who lives have been turned upside down by ICE operations. In Perspective, we spoke to the film's co-writer Marine Pradel.
