Attorney for Harper Moyski's family considering a lawsuit against YouTube after Annunciation shooting

It comes after they allegedly failed to alert law enforcement to disturbing content uploaded by the shooter in the Annunciation School mass shooting last summer. Moyski, and 8-year-old Fletcher Merkel were killed, with numerous other children shot.

Family attorney Greg Francis told WCCO's Adam and Jordana that the shooter posted multiple videos to YouTube that promoted "extremely violent ideologies," with some that glorified racism, antisemitism, firearms and more.

"The family wants to know and understand what exactly YouTube knew, and when they knew it," Francis explained.

He says the media company and "Garry's Mod," a video game owned by Facepunch Studios, have "blood on their hands" after their failure to act on information they had prior to the tragic shooting.

Francis also said the shooter had videos scheduled to go public the day of the shooting including a "violent manifesto" and a diagram of Annunciation Church.

"Certainly, protocols need to be in place for platforms such as this that," Francis adds. "Disseminate information, that dangerous information, is not being disseminated or shared, or planned, any of those things."

A Google spokesperson provided the following statement to WCCO Radio regarding the family's questioning of their practices:

“We have the deepest sympathies for the victims and families of the horrific attack at the Annunciation Church. We removed the videos after detection, and invest heavily in technology and our teams to remove extremist content. We also work closely with law enforcement, other platforms, and civil society to share intelligence and best practices.”

A possible suit likely depends on the interpretation of Section 230 of the Communications Decency Act. That is a 1996 U.S. federal law that shields internet services, websites, and online users from being held legally responsible for information posted by third parties.
