You really need to do your own homework in regards Japanese Internment. [Irrelevant blah-di-blah deleted]

It doesn't matter even if it was limited to two hairdressers in Topeka. So what was the authority under which they were interred? None of the information you gave is relevant to that question of where the authority to do such came from. More misdirection from you. We are trying to answer YOUR question here. Was it a law, presidential decree, military order, or what? Under what authority were they interred?

From Wikipedia:

President Franklin Roosevelt authorized the internment with Executive Order 9066, which allowed local military commanders to designate "military areas" as "exclusion zones", from which "any or all persons may be excluded." Twelve days later, this power was used to declare that all people of Japanese ancestry were excluded from the entire Pacific coast, including all of California and most of Oregon and Washington. Some U.S. residents of German and Italian descent across the country were also arrested and interned when deemed to be security risks on an individual basis (rather than as an entire community). In 1944, the Supreme Court upheld the constitutionality of the exclusion, removal, and detention, arguing that it is permissible to curtail the civil rights of a racial group when there is a "pressing public necessity."[1]

I am not sure the Supreme Court would hold the same today, but then again they just upheld racial dicrimination that the Dims like now so you never know.
