 Well, I think we can't rule out anything, and this is where the FBI comes in. Their investigation, of course, is about much more than just that moment or those minutes or that event, the shooting itself, but rather the investigation of how did it happen, why did it happen, what was the motivation of the shooter, what's his background, who are his friends, and all of the acquaintances, accomplices, all of that. That takes a lot longer.
