It actually doesn't mention that police surveillance of your social media posts calculates a threat score for you, which is used to make law enforcement decisions.
In fact, the article I think does a poor job overall doing compare-and-contrast. It has a paragraph (two?) on the United States, and dovetails into an opinion (without covering America much at all) about why China is worse.
Americans need to understand that they can't fight the Chinese for their rights. They have to fight Washington for their rights.
