How do we know they're the parents if they're not documented? How do we know they're not human traffickers? FWIW when I was 12 my dad drove me across the Canadian border to visit some family, and the Canadian police couldn't verify he wasn't some random kidnapper, so they detained and separated us for hours while they tried to contact my mom (this was before cell phones). A ton of hassle to verify that my dad was who he said he was, but ultimately it was for my own safety. I don't really see the difference, except in the case of the ICE detainees, the parents are also criminals for crossing the border illegally. (Aren't criminals in our own country separated from their children when they're arrested?) Sure downvote me because it hurts your feelings but logically you're wrong.
