Suicide witnessed on the internet

My sympathy goes to the family of this young man who decided to take his own life while on the internet. A Bipolar college student decided to commit suicide on the internet while other internet users watched. Apparently, this 19 year-old reached an emotional low and wanted to end his life. The college student took a handful of pills and everyone watching via internet thought it was fake. Some of them were convincing him to take the pills. I think this could have been prevented had someone intervened that was watching via the internet. Do you think that there should be a law that in the event of an emergency viewers should be responsible for reporting such incidents? Why or Why not?
