Would you have said the same thing about Mark Conditt? Or is there a difference? Should we talk about some murderers and not others? Was he a terrorist? Was she?
We know that reporting on a killer's identity and motives in detail encourages ideation in others. I think it's fine to talk about these people, but context is important.
In this case, it appears to be someone who was frustrated with a lack of social media attention; we should be careful in not rewarding her heinous act in a way that encourages a future shooter.
