After a man posted a live stream of himself shooting and killing an elderly man, Facebook has said it will be reviewing its reporting methods.

On Sunday morning a man went live on Facebook to announce his intent to commit a murder. Not two minutes later the same man posted a video of himself shooting an elderly man before going live one last time to confess to the murder.

“It was a horrific crime — one that has no place on Facebook, and goes against our policies and everything we stand for,” Facebook vice president of global operations Justin Osofsky said of the ordeal that was live streamed on the platform.

A number of users expressed concern that the resulting videos remained on Facebook for almost two hours but, according to Osofsky, the videos weren’t reported.

“We did not receive a report about the first video, and we only received a report about the second video — containing the shooting — more than an hour and 45 minutes after it was posted,” Osofsky explained.

Once a report was received Facebook disabled the man’s account within 23 minutes but after taking two hours to respond to a report the VP admits the firm needs to do better.

Make no mistake, Facebook does have measures in place to deal with content that shouldn’t be on the website such as artificial intelligence which prevents some videos from being shared in their entirety. This AI along with a team thousands of people strong, reviews content that has been reported, but Osofsky says that these systems are being improved.

“Keeping our global community safe is an important part of our mission,” Osofsky concluded.
