I do think in general across the world there has been progress in fighting social injustice and oppression - thanks largely to continuing left campaigning - though obviously it has been set back in many places at times.
But it’s going too far to say that people will simply not accept unjustified police assaults anymore - such assaults are indeed still swept under the carpet, as a glance through some of the recent examples linked in the ‘Met criticised over Clapham vigil policing’ thread clearly demonstrate.
A lot depends on perspective. Western countries tend to emphasise free speech, but are prepared to let hundreds of thousands of people in poor countries die of covid to protect big business property rights (vaccines IPR); they’re alert to the dangers of state control of media in other countries, but hardly ever consider control by big business might be just as problematic.
To see the world as it really us, you have to detach yourself from all such partial, ‘national’ perspectives.
