Sobering note:
Within 4 days of Pearl Harbor, Census records had been used to list 110,000 citizens for groundless indefinite incarceration based on race.
Somehow I’m not buying “won’t do it again, really, promise”.
a) Census admitted it provided block data ("This is an area where some Japanese-ancestry people live")
b) In 1942, Congress passed a war powers act that included a section repealing confidentiality for war purposes
c) Census did provide, in mid-1943 , some specific info on Japanese-ancestry people living in the DC area.
What do you have that is different or beyond that? ("4 days after Pearl Harbor . . . .")
