If one can, I urge visiting one of these camps. You'll see many such photos on display. But for me it took feeling the brutal heat of the surrounding desert in Manzanar. There is no shade, no AC. In the summer, it gets up to 110º. In the winter, it barely breaks 40º. In every photo you'll see a cloud of fine dust on the ground. It hurts.

And the US jailed more than 120,000 Japanese Americans there.

For those who cannot visit, it's worth seeing how inhospitable the location is: https://goo.gl/maps/wz7NTbhMMYTid4b26
