I mean, in a murder investigation, you might go through a dozen people, checking alibis and generally investigating to find the final suspect and convict.
Granted, what happened here was unconscionable for someone that was only being investigated. I can see her being put on administrative leave while it were sorted out to minimize damage if she actually were guilty. But what was done beyond that wasn't right.
But you also can't ignore investigations because people might get upset. Unfortunately China has spent decades committing provable industrial espionage, so it's hard to say you can't go down that road. And when you get that high of a percentage of convictions, it proves that out. Frankly, the Chinese government should be as much on the hook here for what was done to her as NWU because they sure make it hard to be even-handed when it comes to theft of IP.
