Well then yes, Google stock is like $900/share, But is it currently pre-split $9000/share? No. Google processing `metadata' is arguably not insider trading. Google gets to openly play in Mr Market, NSA does not. Game over.
Is that true though? What prevents NSA employees from participating in the market? It's still basically legal for members of Congress to participate in insider trading. It seems like a public corporation would be more likely to be required to play by the rules.
