Not sure what the protest is over but feels like NYC to me.
Found a longer piece that had it from another angle... https://freedomnews.tv/2021/04/02/protester-plummets-after-climbing-bank-wall-in-midtown/
“The protest was originally scheduled to bring attention to big banks in the city who are funding an oil pipeline called Line 3.....Extinction Rebellion are a climate activist group who do creative performative actions for causes.”
Maybe it was a creative performance that the guy was doing... and at the end of it, he goes extinct?
