Striking a much different tone this time, Mark Zuckerberg again commented on a Facebook livestream gone viral. Unlike the cheery Chewbacca Mom video, this was about a stream capturing the immediate aftermath of police shooting a black motorist in Falcon Heights, Minnesota, broadcast by the victim's fiancee from inside the car. The Facebook CEO did not comment on the glitch his company said was behind the video's temporary removal, but closed saying "While I hope we never have to see another video like Diamond's, it reminds us why coming together to build a more open and connected world is so important -- and how far we still have to go."
