Cable news people call them “prison camps” or “Trump prison camps,” but look in any dictionary: prisons are where people convicted of crimes are held. As Merriam-Webster notes, a prison is:

“[A]n institution for confinement of persons convicted of serious crimes.”

But what do you call a place where people who’ve committed no criminal offense (immigration violations are civil, not criminal, infractions)? The fine dictionary people at Merriam-Webster note the proper term is “concentration camp”:

“[A] place where large numbers of people (such as prisoners of war, political prisoners, refugees, or the members of an ethnic or religious minority) are detained or confined under armed guard.”
