Misdirected angst

I just watched a report on the network nightly news concerning the marketing and selling of mature video games to minors. At least half of the surveyed minors said that they were able to purchase adult rated games. I agree that this is not good. The news reporter then interviewed a representative from the video game industry to discuss whether the game rating system works. Isn't that a little misdirected? Why not talk to the stores that sold the games? Getting upset at the game industry about minors purchasing adult rated games is like getting upset with Philip Morris because a convenience store sold a minor a pack of cigarettes.
