That's the point though. Those who do play video games (especially rts and some rpgs) are a bit more aware (for better or worse) than others. Not meant to demoralize but to bring to light the point that those who engage with digital augmentations of reality have more inclination to expand their perception of actual reality. Exorcising that part of the population over and over is meant to demoralize them to the point where they ignore it. We don't need to ignore it, we need to use the pattern recognition, input systems and logical interfacing we do with technology to our advantage and look deeper. Most of us already do, and that's why they continue to use this line like a broken record. Because "gamers" get blamed rather than the politicians who should be taking the blame for not stopping tragedies themselves.
