All things considered, the Hong Kong police did what they had to given their precarious position. Compare the 2 deaths during a year of protesting to the 19 deaths within a couple weeks of the George Floyd protests. Keep in mind that they're stuck with the Hong Kong police even if they are allowed to become independent, so it doesn't make sense to demonize them.
