Completely forgot about that one. That was a very bad one.
Until Anders Breivik came along, I think the Port Arthur massacre was one of the worst in terms of death toll.
I notice a certain tactical similarity between Holmes and Breivik; the bomb, the music set up loud on a loop designed to lure the cops (or someone) who would inadvertently set it off, and then the shooting attack itself. The body armor, the SWAT look of the shooter.
I don’t think Breivik’s little shoot-’em-up in Norway was a direct inspiration, but at the same I do wonder if Holmes took some ideas from it into his head. Certainly, this young man is no dummy; he’s highly intelligent. He might have looked at the general outline of the Breivik attack and thought to himself, “Hey......I could do that too!”
One thing I’m sure about, this wasn’t some spur-of-the-moment incident; this required planning, weapons procurement deliberation, and premeditation.
