I’ve lived here for years and never heard of these jokers.
I keep mentioning to people that here in San Antonio, anglos are the distinct minority. Last figures I saw put the hispanic population at nearly 68%. A mi no me importa, but Balcones Heights has had something of a reputation in the past. ICE holds are generally initiated by ICE, not by the state authorities.
That having been said, what they’re doing is well within bounds under the Vienna Convention on Consular Notification, which requires authorities to ask anyone who gives indicia of not being a US citizen whether they are, so notifications can be offered or made, depending on the person’s country of origin.
