It's not a witch hunt if it actually happened. It's just news.
Is it perhaps the case that the media are now doggedly rooting out this kind of thing in SV because it's pushing page views? Sure. But why does that matter? These incidents are real, and it's about time the silence was broken about it.
Is the media, itself, immune to this kind of thing? Obviously not. Fox News provides ample examples. But, again, why is that relevant in this specific context? Does it make Calbeck's actions less serious? Should the media not pursue these very real stories? Should the victims keep silent?
I'm just trying to understand the thrust of your comment, here... because I honestly don't see where you're going with this. It strikes me as mud slinging just to make sure everyone looks equally dirty, in order to somehow minimize what folks like Caldbeck have done.
