Governments are not fond of admitting mistakes, you might have noticed. It often takes a while, as it did with the federal government and the decision to lock up American citizens of Japanese descent during World War II.
The program was controversial even in its times, but the government still chose to document what it was doing. The result was a collection of photographs by some of the best photographers in the business, now contained in a book called Un-American: The Incarceration of Japanese Americans during World War II. Richard Cahan and Michael Williams collected the photos and wrote the narrative; we revisit their interview from 2017.
