I think the key to this, is to find out why he targeted that country music festival. It was clearly no accident, he deliberately chose it.

I hate rap music, but I'm not going to shoot up a rap concert. I'm beginning to think this is another Charles Whitman. He just wanted to shoot a lot of people, and chose a music festival. If it was political, I can think of a few hundred targets that would be more appropriate.
