Last month there was the story that DHS had basically lost about 1,500 minors who had immigrated unaccompanied by adults. Which is maybe something to keep in mind when John Kelly talks about taking immigrant children away from their parents and putting them in "foster care - or wherever."
I suppose a silver lining is that Trump's sheer loudness on immigration issues has prompted a lot more coverage and awareness of this sort of shit, which has basically been accepted as the mainstream status quo.
