Experts on extremism say the teenagers who opened fire and killed three people at the Islamic Center of San Diego were motivated by far-right conspiracies and white supremacist networks.

Their manifesto includes hateful rhetoric towards Muslims, Jewish people, Black people, the LGBTQ+ community, and women.

They also promoted symbols long associated with white supremacists and Nazis. The shooting is the latest in a pattern of violent, right-wing extremism in the United States.

On Midday Edition, we unpack some of the ideologies that motivated suspects and what the violence says about the state of extremism in the U.S. We also talk about how journalists should report on the tragedy in a thoughtful way.
