Also, another request: Please, please don't watch or share the video or clips of it or anything.
The culprit was a terrorist. The goal was, in addition to the deaths, to cause fear. Watching the video only allows that victory. Just know that the deaths happened: that horror is enough.

The Dangerous Spread of Extremist ManifestosThis article is from February, when we thankfully averted a mass killing. The killing being discussed now was possibly also inspired by the person mentioned in this article.
Hasson is only the latest acolyte that Breivik has attracted in the years since his 2011 attack. Both terrorists and nonideological killers have attempted to emulate him directly, with deadly results. The Newtown shooter Adam Lanza reportedly collected news clippings on Breivik’s attack and other incidents of mass violence before he killed 20 children at the Sandy Hook Elementary School. Other young men, such as the British college student Liam Lyburd, have been inspired to plan or carry out mass shootings based on their admiration for Breivik’s lethality, rather than his beliefs.
