Do Video Games Cause Violence?

I found article online, and being a fan of video games I couldn't help but click on it. It's about video games causing violence, something I've had to deal with most of my life, ever since I was six. In the article it says:

"In a debate that has been raging for nearly two decades, the latest research suggests the impact of violent video games has been overstated. In the new study, Drs. Christopher Ferguson and Cheryl Olson discovered violent video games such as ‘Mortal Kombat,’ ‘Halo’ and ‘Grand Theft Auto’ did not cause high-risk teens (those with symptoms of depression or attention deficit disorder) to become aggressive bullies or delinquents."
