How 'bout the performance of US intelligence? - has to be culpable. Did the same thing with Anthrax - seems what they normally do.
I'm guessing intelligence has failed repeatedly because it functions as an arm of whoever is in office rather than some objective, autonomous, information gathering organization. If somebody says don't go there, they won't go there. If some dickhead politician says kill that line of inquiry, they kill it.
Perhaps intelligence is a misnomer.
