Laptop Shooting Dad vs. Dr. Phil

I have a mixed reaction about the story and would like to hear other people's opinion on this.  But I can say one thing - mentally I can understand the Dad, his motives for doing what he did, agree with his principles about respect for parents and public speech.  But on the emotional level I would not be able to connect to this person, my heart has no desire for men of violence. In a way, the laptop is part of  the girl's essence, shooting at it is an expression of hatred, like shooting at someone's picture.
So it all started with the 15-year old daughter posting hateful retoric about her family on facebook.  I think the initial reaction of any thinking parent would be a surprise, horror and desire to find out why this happened, what have I done to make my child feel this way? Hashem placed this child in my care, how did it come to this? Ask the child - honey, why do you feel so much hate towards me, what have I done, how can I change this?  The 15-year old's post is a cry of despair, a scream to the world, the result of resentment that must have been building up for years. This relationship did not start yesterday.  I agree that the children must respect their parents, but this respect has to be taught slowly and consistently, not in a one-time cruel jesture, and most  importantly a parent has to work on himself to be respectable, to enable his child to respect him.
