Dawn of the Stupid Question

The trouble with question heds is that they have so many answers:

1) Dunno. Since you're the one with reporters and news services and I'm the one with quarters to put in the rack, why don't you tell me?
2) In realist terms? Any of a number of people or organizations who think they can change attitudes or behaviors by randomly killing noncombatants in a highly public way. Or, you know, someone who's just nuts. In a world where punditry was an honest trade, an accurate answer might be: It's either somebody we've heard of or somebody we haven't.
3) What "this" did you have in mind -- standing around holding candles in the air? Because if you don't want the animal brain to think something, don't use a nice big colorful image to cue the animal eyes to set it in motion.

Given all those choices, maybe it would be a good idea to spend that frontpage space on talking about what you know, rather than on showing that you're just as baffled as your audience.
