My only take here (besides the certainty that the shadowy hand of the FISA FISC court is not behind all this) is that it doesn't look like another ICE raid.
I don't think anyone, least of all OP, is suggesting this is what happened.
Everything is rank speculation at this point, but if I were going to speculate I'd speculate that Wang suddenly left the country of his own volition and the employer began investigating his disappearance and stumbled on things that led to them calling in the FBI.
That's still purely speculation, but it would account for the sequence of events and the manner of investigation way better than any ideas about him being "vanished" by the US government.
You don't know if its detained, you don't know if is in the territory of the USA, you don't know anything....If it's a US Citizen would be espionage because?
so you're saying he vanished...?
Yes, as far as we know he vanished, but as far as we know he did so under his own will before the university even put him on leave.
An expert in cryptography seems like someone theyd be keeping tabs on if they really do this.
Just spit balling here and dont mean to accuse the guy of anything.
"Diplomats" just get declared persona non grata and put on the next plane home. Neither the U.S. nor the other country wants to make a fuss.
In other words, they aren't the traitors, their agents are. And those agents are the ones who get tried in the media circuses we're all so familiar with.
The feds execute warrants every day without making the news.
Or they vanish themselves before they're caught and are never heard from again because they got away.
We don't know that anyone has Wang in custody. He was scrubbed from the University computer systems weeks before the FBI raided his house, which suggests that whatever happened started then and built up to this recent raid which finally drew media attention.
Maybe another xenophobic red scare-type U.S. gov't overreaction will inadvertently export top talent to China a second time.
