The plight of undocumented immigrants in the United States has dominated headlines in recent weeks. The deployment of the National Guard to prevent Central American asylum seekers from crossing the US-Mexico border, the murder of Claudia Gomez Gonzalez by a Border Patrol agent, the forcible separation of immigrant parents from their children — the stories keep breaking, like a trickle of blood becoming a hemorrhage.

What’s often lost, though, is the full scope of undocumented immigration, situated in both time and place, from the destabilization of Central America and the rise of the war on drugs to the use of undocumented labor and the deployment of draconian law enforcement in the United States.

That is the perspective offered by Undocumented: Immigration and the Militarization of the United States-Mexico Border, a new book of photojournalism by John Moore, special correspondent for Getty Images. Moore spent ten years covering undocumented immigration, crossing the entire length of the US-Mexico border and traveling extensively in Mexico and Central America. Throughout that time, he documented seemingly every aspect of the 2,500-mile journey north — funerals of children murdered in Guatemala, migrants riding freight trains through Mexico, smugglers casing the southern US border — as well as the reception awaiting undocumented immigrants in the United States: border agents armed with automatic rifles, predator drones preparing for takeoff, vigilantes out on patrol. Combining photographs with brief essays in both English and Spanish, Undocumented provides an expansive view of contemporary undocumented immigration.
