"Live-streaming empowers and implicates the viewer in a way a traditional recording cannot. It's the sheer magic of telling Roger Federer to bend down, in front of a crowd of thousands, to give you a close-up of the grass on Wimbledon's centre court and having him do just that.
But it's also the anonymous goading of a desperate person towards suicide, without regard for the impact of the words, or watching that suicide, or a rape, or a murder, both right before your eyes and thousands of kilometres away, and feeling powerless to stop it.
At its best it's pure, honest joy and at its worst it's sadistic voyeurism. The difference is that it's unmediated and it's live - and we are all involved."
