Apparently Immigration and Customs Enforcement (ICE) in the US has been conducting raids targetted enforcement in major US cities.
A DHS official confirmed that while immigration agents were targeting criminals, given the broader range defined by Trump’s executive order, they also were sweeping up noncriminals in the vicinity who were found to be lacking documentation.
For me, this raises again a question that has genuinely puzzled me for a long time: How many Americans typically carry with them documentation that would show their citizenship, or otherwise prove their right to be in the US? A birth certificate would do (unlike in the UK, where the government has been at pains to show that it won’t even recognise the right to citizenship of people of tainted foreign blood, even if they were born in the UK at a time when everyone thought the law automatically granted them citizenship), or a passport, but most people don’t carry these things around every day. Many Americans don’t have passports, and birth certificates may be hard to lay your hands on at short notice. (Besides which, what good does it really do to show a birth certificate if your name is John Smith — or, let us say, José Garcia?)
