American doctor receives email from immigration officials telling her to leave the country immediately

[RandomNumbers]

42. I assumed the highlighted line means

that if an illegal immigrant ( "alien" ) provided an email address on some form somewhere sometime, that ICE / CBP / whoever got hold of, and that email address was actually for an American citizen - "oh well" ... "mistakes may be made" ... that sort of thing.

It's possibly complete bullshit, but ...

I've seen occasions where people have recommended to give random email addresses in certain circumstances. Who knows what data the fascist regime can access on its targets? What they are saying here, I think, is that someone they "know" to be an "alien" had provide this email address somewhere, and that is why they sent the letter.

(except they weren't responding to this case specifically, just claiming this is the reason this kind of mistake could happen)

Okay that is what I think the line means, but the details are rather insignificant, IMO. The whole process is bullshit, I am sure it is unconstitutional (even though I am neither lawyer or constitutional scholar, but I've read the damn thing, unlike obviously some in this administration). The implications are horrific, particularly combined with the apparent ability of the administration to disappear someone without meaningful challenge.
