Attack America

Freakonomics recently ran a blog asking for ideas on how to attack America.

Are you appalled? Up in arms? Outraged?

Why?

Can you find a better way to brainstorm for attacks we may need to protect against than three hundred million minds looking for gaps in our coverage?

Oh sure, there will be a lot of wasted time, ideas not worth looking at. There will also be things a terrorist might think of the government hasn't.

Make it a government sponsored, public, question (again) and make us safer.
