Why I Published the Shooter Manifesto - Ken Klippenstein:

I think a lot of this talk about copycat killers is a smokescreen obscuring the real reason these outlets didn’t publish the manifesto. As a friend at NBC explained, they did not want to antagonize their law enforcement sources who had provided them access to the manifesto on the condition that it not be published.

Now knowing what the manifesto actually said verse how the news portrayed it when they thought we’d never see it, really made them look bad.
