The biggest difference between now and "then" is the internet and our connectivity, audio and video + live streaming for real-time evidence gathering; yes, I'm aware bad actors are capable of signal jamming in an area or at scale, or taking down the internet - is why the democratic nations and people that are free must strengthen in case of a future confrontation with these bad actors, and likewise technology like mesh networks are expanding - although a nation could block mesh networks too with enough effort - and really then blocking communications is more a signal to the rest of the world that we're dealing with a tyrannical government.
