Well, I think you should sue the paper. I don't think they can print a minor's name without permission. I can't tell you how mad I am over this. If you were closer I would be causing some trouble.
That causes me grief to hear that so I can just imagine how you feel. I'm glad your grandson is still young. This might not get back to him at his age, but let them know so they can watch for it.
Even though I'm angry about this, I do hope that it causes some parent out there somewhere to get help.
Hugs,
MG
