"There are those who, in good faith, believe that we should leave the balance between civil liberty and security entirely to our elected leaders, and to those they place in positions of executive responsibility. Again, we do not agree. The American system, as we understand it, is premised on the idea -- championed by such men as Thomas Jefferson and James Madison -- that government run amok poses the greatest potential threat to the people’s liberty, and that an informed citizenry is the necessary check on this threat. The sort of work ProPublica does -- watchdog journalism -- is a key element in helping the public play this role. American history is replete with examples of the dangers of unchecked power operating in secret. Richard Nixon, for instance, was twice elected president of this country. He tried to subvert law enforcement, intelligence and other agencies for political purposes, and was more than willing to violate laws in the process. Such a person could come to power again. We need a system that can withstand such challenges. That system requires public knowledge of the power the government possesses. Today’s story is a step in that direction."
