I don't think it is odd and I disagree with you. First, if you find too many search results, that is just as bad as not finding any. Secondly, when it comes to this specific issue, the quality of information can range from unusable to thorough based on what article about it you read. Given that "Secret overseas Chinese police force" is such a good headline, there are many many websites and lower tier news sites publishing about this. There seems to be no one catalyst publication that broke this story first. This makes it hard to establish any objective facts about it (for me). On top of all this, there may also be personal bias involved when reporting about it.

Given all this, why is it so odd for me to ask for more information here? Like, instead of discouraging me from asking for more information in the future, you could have listed the sources you feel are usable.
