I'm not sure if these requests are only made if other ID isn't available or a refusal to present id happens. That said, I'm not sure how this qualifies as reasonable suspicion in terms of stopping someone without evidence of some other crime in progress or as part of a warranted raid activity. Though stops on highways within 100 miles of a border is very much permitted for identification, unsure if this would fall under those provisions.
While I absolutely support deportations, this appears at first glance to be over the top... but I'd like to see any clarifying statements from ICE, which I don't recall seeing in the article.
