Law suits and kids

I noticed on Slashdot that there was a case about a 14 year old boy who killed his father and step-mother. Well the case seems simple in the article, abusive parents vs kid who played video games obsessively. Naturally it wasn't any old game but one that has had lots of press .... "Grand Theft Auto: Vice City". This game is well known for it's violent nature.

Now that the case has started what I really want to know is:

How can Jack Thompson expect to pin the problems on the game while the game is rated 17+/Mature? If so Jack Thompson should read this

Where were the parents making sure he wasn't playing games that are rated for three or four years older than him?

What else did the "parents" allow him to do that wasn't suitable?

What happened to personal responsibility?

On a side note I think I have posted too much this month and I'll save anything else for next month....Except maybe tomorrow's meeting.
