Thank you for the question.
Again, everything is open source and online, and can be verified.
We call them “police stations”, in the first place, because the PRC authorities that set them up do. These are, specifically, four public security authorities from four local jurisdictions in China. They vary a bit in the name they use, but they all call them “police linkage centres” or “overseas police service centres”. That's the wording they use. Obviously, the fact that they have been set up by a police body within the PRC is why we adopted that language, as well.
Among the tasks we've listed continually across sources, including newspaper articles appearing online from Chinese Communist Party media, are so-called administrative and consular tasks, which, by the way, the Chinese authorities and even embassies across the world confirmed exist, obviously. They also include tasks such as monitoring and measuring the sentiments or opinions of the community, and resolutely cracking down on crime—assisting public security authorities back in China with cracking down on crime, which, again, leads to those persuasion to return operations. We found direct evidence of the involvement of some of these stations in executing those operations.
