The way I see it, one of two things is going to have to happen before we get even close to video gaming not being a scapegoat.
The first option is that the media - newspapers, news shows, etc - actually start doing their job properly, putting research into the stories they put out and presenting facts rather then possibilities, and not slanting the story to make it seem more scary. This would solve some other problems as well (Vaccine = autism scare, anyone?)
The second is that gaming actually starts getting from respect from the majority of people. The news media and everything stop seeing it as just a toy to be used for education, or worse a killer-making device, and start to see it as something with the potential to be an artistic masterpiece.
Given the way the world seems to be going, though, I'm not holding out hope that either of these changes are coming anytime soon. If it happens within the next 5 or 10 years, I'll be impressed. Hell, if it happens before the previous generation dies off, I'll be impressed.
