As an aside, I wish the WSJ didn’t name the terrorist in their article and instead followed the NZ PM on leaving him nameless. If people really want to know it they can go to Wikipedia.
- Not naming the killer frequently was one.
- Focusing on the victim's lives (basically humanizing them) was another.
- Not playing videos of the chaos and violence was another.
NPR actually seems to be following those patterns too. Not 100% because news is news, but I think news ogrs can follow them, and the information is still free.
What research is this based on? Sounds suspiciously like “computer games cause violence” which AFAIK has been debunked.
If you are a talent-less hack and want to get on the news this is a very simple method. I say that in the hopes that journalists will start excluding information and keeping these people nameless and bland.
