1) Ten people were convicted of spying for Japan during World War II. None were of Japanese descent.

Regarding Hawaii's Americans of Japanese descent, they WERE incarcerated by state and federal agencies without trial. They were incarcerated in mainland camps and I personally am aware of several cases where the male head-of-household was removed from the family and no communication occurred to wife or children for years (while the dad was incarcerated without any charge). This had the effect of debilitating churches and businesses in Hawaii also.
