Jon Hardly, you claim that this kid was, "emotionally disturbed."

I'd say that just about anyone would be emotionally disturbed by grandparents who turn you into police. Whether or not the kid was emotionally disturbed prior to that is not for you to decide.

Why is it a kid can't write in a private journal but violence can be broadcast coast to coast on t.v. or played daily on video games or on computers?

Its a set-up. Society creates it and then punishes their kids for re-enacting it or playing it out.

We watched cops and robbers and played cops and robbers. We watched cowboys and Indians and played cowboys and Indians.
