I wouldn't insult a kid's intellegence by claiming that he can't tell video games from real life. As for the study that claims the video game kids are more aggresive, it could be that the kids are frustrated due to the dfficulty of the games or hyped up by spending too much time on them.
90% of U.S. kids 8-16 are plaing video games, and theres been only a handfull of school shooters. plus, there were school shootings before video games were invented. How does Jack Thompson's "experts" explain that?
