As the documentary And Then They Came for Us demonstrates, the registration and incarceration of Japanese Americans was one of the worst violations of constitutional rights in American history. The U.S. government lied about the threat of espionage to justify the incarceration. Not a single person was ever convicted of espionage or treason. The U.S. Supreme Court upheld the incarceration in the Korematsu decision in 1944. It has remained on the books as valid precedent until this year, when the Supreme Court overruled the decision, but upheld the Muslim travel ban, based on similarly uncorroborated assertions by the U.S. government. As we commemorate the 77th anniversary of Executive Order 9066 which was signed by President Roosevelt on Feb. 19, 1942, the film documents through the use of photos taken by Dorothea Lange and others, the damage this order did to 120,000 people, two thirds of whom were American citizens. The photos by Lange and others reveal the pain and the resilience of the people who were forced to leave their homes, their businesses and their communities simply because they looked like those who had bombed Pearl Harbor. We were at war with Japan and almost no one spoke out against the incarceration. In 1988, Congress passed a reparations bill giving every living survivor, $20,000. Featuring George Takei, the actor and activist, and many others who were incarcerated, And Then They Came for Us, demonstrates the importance of speaking up against any efforts to register or ban Muslims or separate children from their parents at the border today. Knowing our history is the first step in making sure we do not repeat it.
