That is taken away.

Someone in my network - a US citizen - was detained, taken to a city 3 hours away, and held for 10 days before being released. Was quite a while before her family knew where she was.

If you're an American who is visibly Hispanic, it's not at all hysterical. If you're in one of those cities, you do have to worry whether you'll return home when you leave your house.
