CLEVELAND -- The graphics look real. The goal is to kill.

The violence of video games isthe world in which Connecticut school shooter Adam Lanza was immersed in, according to published reports. His favorite video game was "Call of Duty."

Lawmakers likeSen. Joe Lieberman, I-Conn., are now taking aim at video game violence. They're calling for tougher regulations of violent video games, and their exposure to minors.

This week a bill was introduced in the Senate, directing the federal government to research the impact video games have on kids. But does virtual violence lead to real-life violence? "It's far more complex than that," said Dr. Felipe Amunategui, psychologist from Rainbow Babies and Children's Hospital, and an expert in disruptive behavior disorders. "Because if that was truly the situation, we would see far more incidences of problems."

Current research has yet to establish a causal link between video game violence and violent behavior in gamers. "Being aggressive may cause one to prefer those kind of games, rather than the games leading to aggressive behavior,"said Dr. Amunategui.

At The Exchange in Lakewood, there are just as many types of video games as there are opinions about violent video games. "I feel like if we ban video games, what else are we going to ban?" said Haleigh Curlis.

But parent, Mary Beth Page, supports government regulations of violent video games."There's parents out there that overlook things. Somebody's gotta watch out. Somebody's gotta do something about it, " she said.

Store clerk Tylor Carter often sees parents buying violent games for their young children, despite their warning labels for players under 18.

"Every single day I have at least one person buying their kid under 12 a shooter," he said. "It's morally dangerous," said Dr. Amunategui. "That child may be interested in pornography. Really interested. So would you have a problem depriving the child of that?"
