San Diego mosque shooters livestreamed massacre, left 75-page manifesto
San Diego attackers Cain Clark and Caleb Vazquez livestreamed their mosque raid, in which three people were killed, and left a Nazi manifesto.
Assessment
Two attackers live-streamed a mosque shooting in San Diego, killing three people and leaving a Nazi manifesto, identifying a clear ideological motive. The combination of a livestream and a written document suggests an intent to spread propaganda and inspire copycats. Authorities will likely face pressure to investigate the attackers' online networks and whether they acted alone.
