The witness protection thing was a joke to make it clear how absurd what you're proposing is. Clearly
some people got the joke.
Y'all read "CCP Police stations" and your imaginations started going wild. There is no evidence nor is there even an accusation that these "police" stations are used to kidnap US citizens.
> You added the part about exfiltration
.... bro how are they going to coerce someone to leave the country "willingly" if the FBI is looking for that person? His passport is obviously going to get flagged.
And if your answer is "get him a fake passport" then congratulations, you just described exfiltration.
