In addition to filing lawsuits, Thompson has pushed for measures against similar games in a variety of public settings. He wrote a joint article in the "Christian Science Monitor" with Eugene F. Provenzo, a University of Miami professor who studies the effects of video games on children. Originally brought together to provide opposing viewpoints on "60 Minutes" in the aftermath of the Columbine High School massacre, they said they had become friends and were collaborating on a book. They described themselves as having "a shared belief that first-person shooter video games are bad for our children, teaching them to act aggressively and providing them with efficient killing skills and romanticized and trivialized scenarios for killing in the real world".
