You also need to remember — and this is coming from whose last journalism job was assigning and editing true crime for a major network — moms killing kids is *hot* right now. It’s awful, yes, but it’s what people want to read, whether it’s to confirm audience priors or, as with much true crime, to titillate (and anger is as much an arousal as anything).
It’s not an accident you’re seeing these stories. People want them, editors assign them, and a trend emerges — real or manufactured — that more of these types of crimes are happening. Crime is way down. Parents killing kids is comparatively rare to, say, gun homicides. Perception is easy to modify, especially when it runs up against preference.
Instead of having pastors in the pulpits telling you which party to vote for, we need churches in the streets sharing the gospel. Evil is on the march in this country and no politician can stop it, only Jesus can.
