Uber prepared their employees for this:

"At least two dozen times, the San Francisco headquarters locked down equipment in foreign offices to shield files from police raids."

Uber, the paragon of virtue when it comes to following the law.

Actually instructing employees how to interact with government officials is on its own a quite reasonable training. Unless they were instructed on destroying evidence, there is nothing wrong with that. I work at an American company, and we get annual trainings which also cover legal aspects. Most of them are of course just the standard trainings about proper legal and ethical behavior.

The friend referenced gave the strong impression that things did not appear above board. This was a late career individual and stated that they had never seen anything like it.

They didn't provide any details beyond that. It's possible that the individual had just never experienced any legal compliance training, but based on their role I certainly expect they had.

The Economist reported on the "techno-nationalism" driving fear of Huawei in their August 4, 2012 cover story. https://www.economist.com/leaders/2012/08/04/whos-afraid-of-... This has been a long time brewing, though there's been a significant uptick in recent months of worries about China, e.g., Bloomberg's October article where they made up lies about Supermicro.

It makes perfect sense to me that Huawei would prep its employees on how to deal with a raid, and being prepared for the police is not solely the action of the guilty. It tells us that Huawei is afraid of the FBI. It does not tell is that Huawei is afraid of the FBI because Huawei are bad guys.
