You’re going to have a real hard time getting the typical American to buy into this perspective.
The typical American probably sides with the police over protesters in most situations.
The only protesters that can match the police are those with inside support. It's how certain people can demonstrate while carrying rifles without issues, while other unarmed peaceful protesters can be corralled, brutalized, and arrested.
Hong Kong is more or less an island, a small one. China can fill the "1,104-square-kilometre (426 sq mi) territory" with soldiers and police in a heartbeat. Nothing you can do, cops already know the 1000+ leaders of the movement and they will be arrested or killed in the first hours. Etc etc
