Let’s hope you’re right. Xi and his gang are quite capable of North Korean levels of violence.The HK state has used triad gangs to attack protesters, has used undercover cops to provoke violence and have used the riot cops to engage in widespread violence against the protesters.
The protests do not need to engage in indiscriminate violence - there are hundreds of thousands on the streets on a daily basis - the protests have overwhelming social weight. An example - paramedics in the HK hospitals are currently staging a sit-in in the hospitals in protest against police murders of protesters and attempts to arrest protesters attending hospital after assaults by police. This has had a major impact in the police being forced out of the hospitals.
The key at this point is the organised workers - the trade unions in Hong Kong - and the indications are that the rank-and-file trade union members are now putting huge pressure on the trade union leaders to call strikes in support of the protests. This development could well be the key factor in forcing the sacking of Carrie Lam and the abandonment of the extradition law.
