Are they not reporting the entire phone conversation or what? Because I can't imagine someone calling up their workplace, yelling "There's a bomb in the building! Everyone get out!", and then trying to use the excuse that it was because of Grand Theft Auto. If that was really the reason he said it, couldn't he have at least explained that to his co-worker?
"Once upon a midnight clear
I saw the world through eyes of a seer
Through the crystal lens I foretold
The past, the future, and present unfold."
