As with earlier tragedies, the issue isn't so much Facebook's ability to intervene in mid-broadcast (that depends on concerned viewers, which is a problem in itself) as the delay in deleting the videos. It's unclear when people first reported the terrifying clips to Facebook, but the lack of swift action meant that the videos spread widely across social networks and YouTube. One TV station even sparked further outrage by airing a barely-censored version of the footage. While it would be difficult to completely prevent someone livestreaming a murder in the first place, it's evident that more could be done to limit the damage.

Researchers and insiders have already suggested a few options. Short delays would theoretically let Facebook cut off a livestream before people see a nightmarish act, for example. It could also place a higher priority on user reports for live videos than it does pre-recorded clips. No matter what, Facebook will likely want to do something -- the immediacy and accessibility of its livestreaming is convenient, but it's occasionally dangerous.
