There are so much more people need to know
Hong Kong is not China the same way Hawaii is not US (hint: they both are).
Ask people in HK to study and spend more money on science and innovation not on property speculation and get rich quick scheme.
Singapore learning from Hong Kong in early years already surpassed it by miles by doing just that focusing on basic health, education and house and avoid letting it's people stay hostage to rich billionaires.
Protests are just symptoms of that simmering discontent with underlying house, education and healthcare problems. This cannot be resolved by relying on old ways in which Hong Kong got rich due to closed mainland China.
1. For governments worldwide:
1a. Freeze the assets of senior officials of the Chinese and Hong Kong governments who violated human rights, in the style of Hong Kong Human Rights and Democracy Act of 2019.
1b. Stop exporting crowd-control equipment to Hong Kong which could be used by the Police Force.
2. For citizens worldwide:
2a. Urge your governments to do the above.
2b. Stop collaborating with China in the research and development of surveillance technology, which is being used also in Xinjiang.
2c. Purchase goods and services not from Chinese sources.
Or you could do the unwise thing and go there and just walk around. When you'll get beaten up because the chinese government is letting the local mob go and beat random people, that should make a case. Maybe journalists could pick that up.
I would really discourage that. There are strong signs that the People's Armed Police might intervene (they are already staging/exercising in Shenzhen). It could turn into another Tienanmen Square situation.
