One doesn’t need to be in Arizona to be hassled by federal immigration authorities, they’re more than happy to oblige right here in in New York. A Times reporter riding Amtrak from NYC to Buffalo witnessed it firsthand when Border Patrol agents asked her if she was a U.S. citizen on a train that wasn’t even crossing any international borders. Evidently, this is a common process and while passengers can decline to answer, they better do so in perfect English or their silence can possibly be used against them.
