One day, God willing, my grandchildren will click open their history textbooks and read about the Central American migrant internment camps. They'll learn about sick kids, locked in cages, kept hungry and dirty and cold for weeks on end, and they'll be horrified.

"Bubbie," they'll say, "how could this happen in America? How could there be toddlers sleeping on the ground without blankets, without soap or toothbrushes to clean themselves?"

"I don't know. I wish I had done more. I'm ashamed," I'll say. We will all have to answer for this atrocity. But some of us will have to answer more than others. Not just the archvillains like Stephen Miller and John Kelly, but the people who kept right on doing their jobs, even as those jobs morphed into defending concentration camps.
