Yes, I know it well. I remember a very striking moment during some protests in London. The GB news was presenting it as having turned violent, with close ups of protesters clashing against the police. At the same time many individuals who were at the events themselves were able to broadcast on social media showing thousands of people peacefully walking together in a very positive atmosphere totally unaware that a small alteration had taken place elsewhere on the fringe of the event.
