Subject: Re: been warning about this for a while
The shocked outrage in the OP article is due in part to the article author - or at least the ACLU rep quoted in it - not being aware that LPR's and other legal non-citizens are, in fact, legally required to have proof of their immigration status on them at all times. And yes, you can get a civil violation and a fine if you don't comply with that requirement. That is different than the rules for citizens, but it's been that way for decades.

I used to carry my "green card" in my wallet next to my driver's license. It was very unsettling when I received citizenship and had to hand it in.
I felt kinda naked. No protection. Got used to it.
