People will look for any scapegoat they can find, whether it be gun control laws, or blaming violent video games. The stupidity is just starting here.
Right before this happened there was an elementary school stabbing I was reading about where like 20+ kids got slashed by some maniac who went berserk in China. It kind of demonstrates that availibility of firearms, popularity of "shooter" video games, and other things have nothing to do with it. People are going to find ways to do this kind of crap if they decide to for whatever reason.

I've heard as many as 33 in some cases.
At any rate, it seems to be largely overlooked due to the American tradgegy right now, which I guess makes sense since less people seemed to die in China, and the media and such there is very draconian to prevent these kinds of circuses.
The conspiricy theorist and horror fan in me has been looking for some kind of connection due to the coincidence, but I haven't been able to come up with any workable theories.
The overall point is, the anti-video game loons will use their favorite whipping boy to vent frustration over any tradgegy. As will the naive anti-gun proponents when a firearm is used, ignoring that firearms don't really matter to these cases (not even making it easier or happening more often, school stabblings like this have happened a lot in China, looking into it I've found articles going back to like 2010 about these kinds of rampages... and this is despite the Bamboo Curtain, making me think it happens even more frequently).
