Mizue Aizeki

Interim Executive Director

Mizue guides IDP’s local and state policy work on ending injustices–including criminalization, imprisonment, and exile–at the intersections of the criminal and immigration systems. This work focuses on ending the police-to-deportation pipeline, ICE policing practices and ICE surveillance, and includes IDP’s campaigns to end the growing entanglement between local law enforcement and ICE. Mizue was one of the leaders in the campaign that led to Governor Cuomo’s suspension of NY state’s participation in ICE’s “Secure Communities” program in 2011 and subsequent campaigns in New York City to limit collaboration between the NYPD and the NYC Department of Corrections and Immigration and Customs Enforcement. Mizue coordinates IDP’s community defense work and also IDP’s work fighting the growing police surveillance state. Mizue has organized around racial justice, workers’ rights, and the policing and deportation of immigrants in the interior and at the U.S.-Mexico border for over twenty years. Mizue is also a photographer whose work has appeared in Dying to Live, A Story of U.S. Immigration in an Age of Global Apartheid (City Lights Books, 2008) and Policing the Planet: Why the Policing Crisis Led to Black Lives Matter (Verso, 2016).
