Today is Civil Liberties and the Constitution Day in Hawai‘i, honoring the birthday of Fred Korematsu, the man who challenged Executive Order 9066 in 1942. That order allowed over 120,000 ethnic Japanese to be incarcerated during WWII. Seventy percent of those prisoners were American citizens. This detention is recognized as a clear violation of civil rights, but Americans at the time did not protest, and scholars today ask whether something like that could happen again.
