Re: Errr, censorship?
"So imagine an alternative world where Facebook had a 1 hour delay on uploaded videos. At 13:40 this nutter goes on the rampage, uploading video as he goes. At 14:40 his video goes live. At 16:00 the police figure out who he is. The video has already been live for over an hour."
It depends on what the one hour is used for. A buffer to give time to stop it being distributed at all means t doesn't go live.
Presumably the alarm went up fairly quickly. If FaceBook, YouTube and the rest sere prepared to set up a system to cooperate there might not even be a need to set up a huge operation to take advantage of that hour to check every video from everywhere. They'd have an hour, or the best part of that, to check what's in the buffer from that geographical area (OK VPNs could be a problem) and feed it back to the police instead.
