Actions of the government (or other actors WRT policy changes) are given legitimacy by serving as a response to perceived existing problems.

(2) The content the shooter generated and streamed spread widely across nearly all distribution channels (FB, youtube, reddit, etc) despite censorship efforts,
(3) We know that wide distribution of the extremist type of content that this guy distributed (whether its white nationalist, ISIS, or anything) in his actions inspires more people to extremism.
