This is the link to an interview, in Norwegian, where I say why we shouldn't blame games for what the wannabe did 22nd of July. The journalist understood what I as saying, and managed to communicate that well, all down to the fact that I consider speculation about whether or not games influenced the n00b to be - speculation.
For those of you who came here in order to find proof that my mind has been numbed by too much gaming, if you read Norwegian, why don't you go have a look at this very good description of how a skilled computer gamer thinks. As you will see, "kill, kill" is not on the gamer's mind. It's more along the lines of "optimise routine, check numbers, remember cooldowns, check threatmeter, move with the team, maintain healer safety, balance the output."
At the same time, I don't manage to care that much. In a way, if it makes people feel good, they can blame games all they like for me. They can blame the weather, the radioactive rain after the accident in Tjernobyl, a really bad streak of losses for his local football team, Fox news brainwashing (that's my favourite theory) or the colour pink. Perhaps he was poisoned by his own make-up. It doesn't change what happened. Also, it won't help us avoid these things happening again. It is an anomaly, something totally unexpected and unpredicted, something so far from the minds of regular people that we can't explain it or avoid it.
The only thing we can do, is not to act the way he wants us to. He added those computer game links to his new facebook profile for a reason, just like the deleted the old profile in order to hide what he claims to have been 7000 facebook friends. He wants us to chase down all kinds of paths, causing fear, anger and confusion looking for a reason. The cause is simple: He had a political agenda, and was sufficiently single-minded and ego-centric to go through with it, in an absolutely ruthless fashion. What made him into this monster? We will probably never know. Genetics, upbringing, socialisation - a bit of all, is my uneducated guess.
However, if you feel comforted by keeping your children away from computer games, please, do so. Personally, I take greater comfort in having kept my children away from handguns, single-minded political rhetoric and religious fanatics of any colour, while brainwashing them with analytical thought until they question everything and look for the peaceful middle way in conflicts.
