enough black sheep in the police force who abuse their power have been creating a vicious cycle of illegally exerting violence on innocent residents -> more resident discontent -> those black sheep take their abuse to a higher level backed by their public relations officers who openly lied in their daily press conference; and the junior police union, against police regulations, had the audacity to write an open letter to the Chief Secretary of HK (2nd in line here) criticising him) -> more resident discontent...this will never end unless those who enforce the law take the first step to stop breaking the law. Or else police will continue to not gain support from residents here (a recent survey found that > 50% of residents gave hk police zero mark of trust). Of course this is only part of this, aside from stopping police abuse and violent protesters from damaging properties, the turmoil would only end if all residents would be objective and condemn violence from all sides, and not blindly sticking for police
