Yeah, I feel for this guy but I don't think anything improper happened here. The law, which is not crazy, is that if you're born abroad you only get citizenship from a US citizen parent if that parent or their parent lived in the US for a while.

Yeah, his dog being taken, getting his hands ziptied, and being sent to a place where he never lived, no impropriety there

I'm speaking of the fact that he was deemed a non-citizen, not his treatment by ICE in the course of deportation.

He perhaps could have been naturalized later, once he was a US resident child of a US citizen parent, but he wasn't.
