If they were blaming gaming it would have been there to begin with, sort of like another article that was discussed on The Escapist not too long ago where a guy allegedly killed his wife over Grand Theft Auto (even if the text of the article shows a differant cause). Simply put if the writer was after that kind of attention they would have worked it in immediatly.
That said, I agree that it was probably some statement about our rather lax immigration policies and how we've been failing to adapt the immigrants we already take to our society.
In general I'd suspect we won't hear much about it simply because to put the incident up for more analysis might lead to conclusions that our more liberal leaders (who are currently in power) won't paticularly like. Not a paticular criticism on them here, simply that this is how things seem to work in general.
I'd also point out that what this guy did with his car is a pretty standard tactic, it's not something that was invented specifically for GTA. *IF* I ever intended to go into a building to shoot people, which will probably never happen, I'd probably do something very similar, and video games would have nothing to do with it.
