For an organization that prides itself on secrecy and security, this is what failure looks like. It is a testament to Alexander’s power that he still has a job.

The second school of thought is that it’s the administrations’ fault -- not just the present one, but the most recent several. According to this theory, the NSA is simply doing its job. If there’s a problem with the NSA’s actions, it’s because the rules it’s operating under are bad. Like the military, the NSA is merely an instrument of national policy. Blaming the NSA for creating a surveillance state is comparable to blaming the U.S. military for the conduct of the Iraq war. Alexander is performing the mission given to him as best he can, under the rules he has been given, with the sort of zeal you’d expect from someone promoted into that position. And the NSA’s power predated his directorship.

Former NSA Director Michael Hayden exemplifies this in a quote from late July: “Give me the box you will allow me to operate in. I’m going to play to the very edges of that box.”

This doesn’t necessarily mean the administration is deliberately giving the NSA too big a box. More likely, it’s simply that the laws aren’t keeping pace with technology. Every year, technology gives us possibilities that our laws simply don’t cover clearly. And whenever there’s a gray area, the NSA interprets whatever law there is to give them the most expansive authority. They simply run rings around the secret court that rules on these things. My guess is that while they have clearly broken the spirit of the law, it’ll be harder to demonstrate that they broke the letter of the law.

In football terms, the first school of thought says the NSA is out of bounds. The second says the field is too big. I believe that both perspectives have some truth to them, and that the real problem comes from their combination.

Regardless of how we got here, the NSA can’t reform itself. Change cannot come from within; it has to come from above. It’s the job of government: of Congress, of the courts, and of the president. These are the people who have the ability to investigate how things became so bad, rein in the rogue agency, and establish new systems of transparency, oversight, and accountability.

Any solution we devise will make the NSA less efficient at its eavesdropping job. That's a trade-off we should be willing to make, just as we accept reduced police efficiency caused by requiring warrants for searches and warning suspects that they have the right to an attorney before answering police questions. We do this because we realize that a too-powerful police force is itself a danger, and we need to balance our need for public safety with our aversion of a police state.

The same reasoning needs to apply to the NSA. We want it to eavesdrop on our enemies, but it needs to do so in a way that doesn’t trample on the constitutional rights of Americans, or fundamentally jeopardize their privacy or security. This means that sometimes the NSA won’t get to eavesdrop, just as the protections we put in place to restrain police sometimes result in a criminal getting away. This is a trade-off we need to make willingly and openly, because overall we are safer that way.

Once we do this, there needs to be a cultural change within the NSA. Like at the FBI and CIA after past abuses, the NSA needs new leadership committed to changing its culture. And giving up power.

Our society can handle the occasional terrorist act; we’re resilient, and -- if we decided to act that way -- indomitable. But a government agency that is above the law ... it’s hard to see how America and its freedoms can survive that.
