I rarely read a post that makes me boil so much. Not because I disagree with what you are writing because everyone is entitled to their own opinion. But it is clear that you have absolutely no idea what is happening in Hong Kong, and what you are writing about.

1/ You do not need to read a research to know that the HK government is a major shareholder in the MTR. That is a well-known fact by anyone who is familiar with HK

2/ Your comment

it is to Protesters advantage to attack many people at such places

The protestors do not attack as many people as possible, and they do not attack passengers inside the MTR. Do you know what happened on 721 and 831? Who was attacking who? Check out those events before you make that statement again.

3/ Your comment

the Police have also executed their work effectively, by closing the MTR Station, other major stations and Subways for further destructions'

Do you know why the police close the MTR stations? First of all, and it is unlikely you know this. The police have no authority to close the MTR, that responsibility and decision lies with MTR. Secondly, closing the stations have nothing to do with protecting the station assets. It is a police tactic to stop the protestors from leaving to make it easier for the police to arrest them.

At some points, the police had to fire tear gases to calm down tensions by protesters

Do you know how many tear gas have been fired by the police? Over 6000 in the past six months, and on 5 Aug, they fired 800 rounds on a single day. The police are known to have fired tear gas indiscriminately at normal citizens who are just going about their normal day to day business. They fire tear gas at protesters in enclosed areas, which is against the policy to use tear gas to disperse crowd. They fire tear gas even when there is no one within the near vicinity just because they feel like it. And have fired tear gas in all but one district in HK. Tear gas is no longer used for crowd control, but for the police to entertain themselves.

5/ Your comment

At some point, protesters were complaining being sprayed with pepper by the police work force.

Is there anything wrong with this when the police points a pepper spray right in front of your face or pepper spray defenseless citizens and elderlies?

6/ Buzzfeed is more of an entertainment digital platform, not the best to use as a reference to write about the HK protest, particularly when it is obvious that you know little about it. If you want to know more about the HK protest and write decent articles about it, I can recommend you read the following:
