Dylan Klebold's parents walked in on him when he had a shotgun under his trench coat and later saw a rifle butt sticking out of his bag.  Eric Harris' father thought nothing of it when a gun shop called to tell him the clips he'd ordered had come in.  He simply said he hadn't ordered any.

"If he had asked whether the clerk [at the gun shop] had the right number," said Eric Harris before the shootings, "we wouldn't have been able to do what we're going to do."

If either of these kids' parents had recognized such warning signs, the Columbine tragedy might never have happened.  Harris and Klebold were making bombs and ordering weapons, all in preparation for a private Armageddon, right under their parents' noses.  How could anyone seriously believe a law against kids getting video games would've stopped them?

The truth is, video games can help children learn about computers, develop valuable skills and build self-confidence.  But, like any toy, they can also be used improperly - and that's when it's a parent's responsibility to notice something's wrong. 

There are already laws against minors buying and consuming alcohol, yet Eric Harris had a bottle of Jack Daniels in one of the videos he made detailing his plan.  Laws making video games "adults only" would be similarly ineffective.  We can't legislate away the things that turn kids into killers. Parents must take responsibility, and pay better attention to the task of raising their children.
