There will always be people who blame that which they don't understand or which makes them uncomfortable. People don't just blame D&D, they blame the music someone listens to or the video games they play or the company they keep, among many other things.
Yes, there are still people who cannot get over blaming D&D for stuff. I work in the legal field and there was a case not too many years ago where the investigating detective listed the books the defendant had on witchcraft and D&D as if they were the same thing. The defendant's choice in music and display of heavy metal posters was also cited by the detective. (This was in the investigation. I don't know that it ever got before the jury.)
Ultimately, there are many folks out there who need to blame something tangible for a violent action, rather than blaming the person who committed the action or trying to figure out what actually caused them to become what they did. It's simply easier to say, "Well, he had a My Little Pony poster in his room, so that must have warped him," rather than to try and understand what really happened. There are also some people who seem unable to really blame the perpetrator and so need to find an excuse, whichever excuse is fashionable or convienent. Such people will always exist.
Since claiming something like this makes a better sensation for the news headline, we're going to always see such garbage in the news as well. Face it, "Video Gamer Goes On Rampage," reads far better than, "Youth who had issues that haven't been addressed or understood, which devloped in a complicated way due to a large number of factors, who everyone around them claims never had any warning signs, commits acts of violence for no apparent reason that we could figure out in our five minutes of investigating this before we had to start filming."
Yeah, I'm a bit cynical.
