There were 127,00 Japanese-Americans involved mainly from the West Coast along with 10,000 German and Italian Americans. 62% of the Japanese were US citizens. 30,000 of them were children.
Living conditions were problematic. There were educational facilities and organized sports, but very spartan and demeaning conditions. It was a disgraceful episode in our history. Reparations were paid out, about 20K per person, far from covering what they went thru. There was an FDR Executive Order that was challenged in court and SCOTUS upheld the EO. So at least there was some legal patina for the action.
The house arrest in WI affected 8 million people. The Governor issued an edict not approved by the legislature or the courts. Schools
and businesses were shut down. Freedom of movement and assembly were curtailed including holding religious services. In terms of civil liberties the shutdown could be considered more restrictive than inside the relocation camps.
If you read the article, the judge was making the point that like what happened with FDR and the treatment of the Japanese and others, the shutdown was a hastily put together action that failed to consider the impact on our Constitutional rights. It was wrong then and it is wrong now.
Absolutely. No questions.
However, in drawing the comparison, one needs to be careful not to equate the level of damage suffered currently, to the level of damage suffered under E.O. 9066. It's apples and oranges.
