Facebook has gone out of its way to help law enforcement officials identify those who participated in the January 6 riot at the US Capitol, the company said in a Thursday conference call with reporters.

“We were appalled by the violence,” said Monika Bickert, Facebook’s vice president of content policy. “We were monitoring the assault in real time and made appropriate referrals to law enforcement to assist their efforts to bring those responsible to account.”

She added that this “includes helping them identify people who posted photos of themselves from the scene, even after the attack was over” and that Facebook is “continuing to share more information with law enforcement in response to valid legal requests.”
