The Wall Street Journal reports that the rampage killer Jared Loughner was a gamer. As usual? Recall Mr. Cho, whose killing of Hokies was followed immediately by angry denunciations of the game industry for programming him thusly. It turns out that the only game in his troubled mind was Sonic the Hedgehog. I guess Sonic only seems to be a cuddly rodent; he's actually the vehicle for a secret code that turns ordinary people into frenzied savages.
Loughner's preferred game was a MUD called Earth Empires. Aha! Now we get to the root of things! Richard Bartle, what insidious mind-altering snippet of code did you hide in MUD1 that has spread across the gaming industry and caused all these murders? Come clean, you rogue hacker!
On a serious note, it appears that Mr. Loughner's MUD community was more supportive and helpful to him than the world at large. He got kicked out of jobs and school, but one gets the impression from WSJ's report that EE forum readers never stopped trying to engage with him or give him advice. Certainly - and this is critical - none of the gamers encouraged him in his ravings.
