Spelca, you're looking at this through the eyes of a juvenile, not as a parent, or other form of legal guardian. I can find no fault in the grandparents looking through his things, that's called being involved in their life and ensuring that you know what's going on. They probably skimmed it to see what was going on, saw the extreme amount of violence and got worried.

I feel they should have confronted him about it, but then again nothing legally says you have to, even in cases of things like sexual harrassment you are NOT required to confront the person if you report it to a higher power. Doing so would have prevented nearly all of the issues brought up by the article, but if he had a history of violence, well known grudges against the people in the story, etc it could all have led them to fear some sort of attack was imminent. At this point it's in the hands of the court to prove that the writings are harmless, but it probably should/could have been handled without getting law enforcement involved.
