The real issue is close to this. The real issue is that when the organization is empowered it's up to an individual to say "no" to improper surveillance. That's what's wrong with the "well there are good people behind it and we are all on the same team" argument. When it becomes your job to prevent an attack, and you have the authority to spy more than you think is morally correct, do you spy anyway? Or are you willing to let 3000 people die, and face the music of the world knowing that you could have prevented it but chose not to for altruistic reasons. That's why the laws must change: to protect the people who want to do the right thing.
