OK I'm expecting a tirade of defensiveness from outraged GTA (that's Grand Theft Auto for those not in the know) players for even daring to suggest any linkage whatsoever between violent video games and the loosening of self-restraint that led an aggressive disgruntled ex-employee to kill 12 workmates at Washington Navy Yard. No doubt the NRA are going through their records making sure he wasn't a member, too. Unfortunately he was black, giving racist apologists for his actions the excuse to blame them on negritude rather than badness.
No, I've never played GTA and don't want to. Back in the 1990s I played a crude shoot-em-up called I think somewhat improbably 'Wittgenstein' in which the victims' Naziness was supposed to excuse the tasteless blood splatter. After that, none. And I've never understood the perverse dual standard that makes it OK to sell video games in which you kill people horribly but illegal to sell games in which you make love with them (and no I don't play those either).
It's just a bit sick, that's all. The whole genre just induces a little unpleasant vomity taste. Which will remain no matter how many GTA-playing but otherwise spotlessly idoneous Anglican clergy that correspondents produce.
UPDATE - You'd need a heart of stone
