Facebook's policy director says the company failed to detect the alleged Christchurch gunman's livestream due it not being "particularly gruesome", the Daily Beast reports.
Brian Fisherman reportedly told US Congress members Facebook did not detect the massacre because there was "not enough gore" in the video for their algorithm to catch it.
The accused gunman used Facebook's live streaming platform to broadcast the massacre on March 15, which left 50 people dead.

The Daily Beast, an American news site, reports representatives from Facebook, Twitter, Google and Microsoft met with members and staff of the House Homeland Security Committee for a briefing on March 27.
Fisherman, Facebook's policy director, was reportedly challenged in the meeting on the livestream.
One Congress member said the video "triggered something inside him" while another said it was so violent it could have been footage from Call of Duty, the Daily Beast reports.
The massacre is filmed from the point-of-view of the accused gunman's helmet, and shows the accused gunman driving to the Al Noor Mosque, entering, and shooting inside.
The footage was live on Facebook for 17 minutes, and stayed there for another hour. The stream was then re-uploaded successfully to the social media site more than 1.5 million times.
The livestream has now been deemed an objectionable publication in New Zealand.
