Tule Lake was one of ten American concentration camps established during World War II to incarcerate 110,000 persons of Japanese ancestry, of whom the majority were American citizens, behind barbed wire and guard towers without charge, trial, or establishment of guilt. These camps are reminders of how racism, economic and political exploitation, and expediency can undermine the constitutional guarantees of United States citizens and aliens alike. May the injustices and humiliation suffered here never recur.
