Without an idea of how many cases were not dropped, it's hard to understand how valid what I feel you are implying is. There will always be false positives, so the existence of false positives is not surprising. It's upsetting and those people are owed reparations, but it wouldn't be unexpected. Without any context it implies that the US is going on nationality motivated witch hunts, which might be true, particularly in the Trump era, but I also would be astonished if China did not have significant penetration into academia and American companies. We know based on China's cyber operations that they are particularly interested in industrial secrets. Given the existence of Chinese police operating on US soil, I doubt the characterization of witch hunts. I've read more than one compelling case of Chinese operatives courting IP theft too, including hearing one on NPR, which isn't exactly a conservative mouthpiece. China openly used organized crime to attempt to put down protests in Hong Kong in 2019. China has a history of arbitrarily arresting foreigners. > We’ve now reached the point where the FBI is opening a new China-related counterintelligence case about every 10 hours. Of the nearly 5,000 active FBI counterintelligence cases currently underway across the country, almost half are related to China. -- FBI director Christopher Wray, July 2020
