And if you don't see that as human rights problem, consider you're wasting your finite intelligence resources on dead ends and so you're not finding the traditional spies that's just some dude that's been bribed.
On a more general note:
Your style of argument is really tired. Who is going to commit wrongdoing on the part of the Chinese government if not mostly Chinese people? You can always try to reframe the issue as one of discrimination, since most of the offenders are bound to be Chinese. It’s pointless.
It's also clear that ethnically Chinese people have been specifically targeted.
Anming Hu is a Canadian citizen born in China, who was a professor at the University of Tennessee. The FBI got him fired before he even went to trial by telling the University he was a spy. In the end, all the FBI actually had on him was that he hadn't reported a small speaking fee on an official form. It wasn't even obvious if reporting the fee was necessary. The whole thing turned out to be a racially motivated fishing expedition by some local FBI agent, and Hu was acquitted. But the FBI majorly screwed up his life and career and smeared him in public first.
A lot of the cases have turned out to be like this. See Gang Chen's case at MIT. That one is almost Kafkaesque, when you read the charges and then read the background.
