A thought experiment: It is very much in vogue to depict the administration's post-9/11 enforcement policies as risking, or actually making, "the same mistake" as the Roosevelt administration made in incarcerating the West Coast's ethnically Japanese population, and as the Supreme Court made in upholding that policy against constitutional challenge in
Korematsu v. United States.
This website certainly implies the point, as does
this one, and the law reviews are beginning to fill up with articles making the claim too (though I can't link you to those).
This claim (and recent events) place an unusually sharp focus on the question of what, exactly, "the mistake" of the Korematsu opinion actually was. One understanding of the mistake was that it was a simple error of inference: the claim is that it was both irrational to infer
anything of concernabout a risk of subversion on the simple and unadorned basis of Japanese ancestry. This understanding of the mistake of Korematsu folds nicely into current claims about the irrationality of racial profiling by cops: there just isn't anything at all suspicious about "driving while black," and it's therefore invariably a legal error to take any sort of official action on that basis.
A related claim is that the mistake of Korematsu was not that it was flatly irrational to infer anything of concern from the fact of ancestry, but that it was
impermissibly selective to cabin the inference to people of Japanese ancestry, when, as a formal matter, people of German and Italian ancestry posed the same risk in 1942.
These are the commonly voiced accounts of "the mistake" of Korematsu. But there are others we don't hear as often (or at all):
1) The mistake of Korematsu was that it permitted an inference about risk of subversion to spill over the line between aliens and citizens. (Of the nearly 120,000 people of Japanese ancestry evicted from their homes in 1942, about 70,000 were U.S. citizens, born in the United States, and the overwhelming majority of that 70,000 had never even stepped foot in Japan.)
2) The mistake of Korematsu was not that it tolerated government action on the basis of an inference from national origin and ethnicity, but that it endorsed
enormous deprivation on people--aliens and citizens alike--on the basis of that inference.
3) The mistake of Korematsu was that it allowed the government to proceed against an entire group of people on the basis of an inference from national origin and ethnicity rather than demanding individualized assessments of loyalty and risk of subversion.
And there are undoubtedly others that I'm not thinking of as I type this.
So here's the thought experiment: Imagine, separately and one by one, that the government's 1942 program had fixed each of these problems. Would we look back on this hypothetical Korematsu decision today and not consider it a mistake?
I'm puzzling this through, and would be curious to hear some answers from others. I'll post more as I continue puzzling.
