To prevent her escape?
Seriously. One plausible explanation for the Hunter laptop is that he wanted out. But Hunter knows that asking to leave is likely to end in a short retirement.
Just like the Mafia...and the Roach Motel.
No; I believe Mrs. Zuckerberg (nee Dr. Priscilla Chan. M.D.) is held out of the limelight PRECISELY because she is ethnic Chinese.
China is NOT a favored nation by most Americans! Her exposure to more Americans would NOT sit well, IMHO, and would bring unfavorable publicity to Zuckerberg who seems to be under the thrall of the Chinese Communist Party (CCP). Witness how Facebook handles issues Zuckerberg/CCP do not like!
HST, Hunter may well be, as you hint, a dead man walking.
I can only conclude that the FBI is corrupt, and is doing the bidding of the Democrat/CCP/Zuckerberg/Soros/Bloomberg cabal!
That is a hard call, but what we are seeing is clear and present evidence of massive corruption/collusion at the highest levels of government, the media, and the LIEberal Democrats!
