It’s true that if you need to tell someone important information, than it is not loshon hora, like many posters have mentioned.
But the Torah isn’t this type of thing where it says: “Here’s the exception, so go do whatever you want with it”.
There halachos of what information is muttar to say and what isn’t. What details need to be mentioned and what don’t. Not every single detail and juicy word is relevant to get the point across. The wording of the article, and of the headline also need to reflect that too.
So yes there’s things we NEED to talk about. It’s not about that, it’s about HOW we talk about them.
