There's an unequal power dynamic. There's been excessive aggression on both sides. There are many example of the police using far excessive force, of shooting tear gas in MTR stations, of terrorizing innocent bystanders when going after protesters.
If the protestors are prosecuted for what they did, but the police get to walk away, it's unacceptable to them. They won't accept it.
