Why is "Timeline of the 2019–2020 Hong Kong protests (July 2020)" trending?

Wikipedia Overview

The month of July 2020 in the 2019–2020 Hong Kong protests began with a turning point in the evolution of the protests, brought about by the Hong Kong national security law. The law, which had been passed by the Standing Committee of the National People's Congress of China on 30 June and come into effect on the same day, was widely seen as having the purpose of curbing opposition, in a broad sense, against the Chinese Communist Party in the city. The law had direct relevance to the protests, as it prescribes harsh penalties for the tactics that protesters had commonly used. Nevertheless, sizeable protests erupted throughout the city on occasion of the 1 July protests the next day, resulting in about 370 arrests, including at least ten on charges under the new law. The Hong Kong government, faced with the task of implementing a law that had been drafted and promulgated without substantial involvement by its own officials, was seen widely, including in the academic and media sectors, as being unable to draw a clear demarcation line between which acts would constitute punishable offences under the law, and which would not. The vagueness of the law, while refused by the city's police chief, was seen by pro-democrats and observers as a deliberate device to amplify its deterrence effect.
