Meh livestreaming it isn’t that big a deal.
I can watch tons of videos of police killing people (some justified, some not), isis beheadings, or just random deaths, easily. Adding public executions which specifically have witnesses most of the time to ensure the state acted fairly, to the mix isn’t that big a deal.
The modern era is screamish about state executions, historically people used to watch them as a spectacle. Christopher Lee famously watched the last public one France had.
