What a weird attempt at semantics. They "target" people based on skin color/appearance/attitude/language, completely ignoring the legalities.
Thats the issue.
It is not semantics. They are not doing any such "targeting"; they are using this information among other factors, in a context where it objectively is rational to use that information, and it has already been found in court (hence "Kavanaugh Stops decision") that this is lawful. (Granted, this is only a stay against an injunction.) I gave details at https://news.ycombinator.com/item?id=45581400 .
It demonstrates carelessness in only targeting people whose presence is illegal, with legal residents being collateral damage.
