Last year, the president the intelligence community a question: Is it possible to create software that would enable targeted surveillance to act as a substitute for dragnet surveillance? In response, the National Academies released a report which you can read .

Unsurprisingly, the report found that there is no such "technological magic." In other words, there is no software solution that results in targeted surveillance being an exact substitute for bulk surveillance.

But, it would be a mistake to misinterpret this finding as justification for continuing dragnet surveillance or rejecting reform efforts. Such conclusions both misread the report and ignore the core of the surveillance debate.

One, the National Academies did not find that existing mass surveillance programs have been effective intelligence tools. For example, it does not rebut findings by the , , and others that the domestic nationwide call detail record program has never stopped an act of terrorism or led to the identification of a terrorist suspect. Indeed, the report does not even attempt to provide one concrete example of a case where bulk collection was essential to a national security investigation.

What the report says is that information collected in bulk, and retained indefinitely, could theoretically be of use in a terrorist investigation. But, it doesn't suggest that this theoretical possibility has happened, is likely to happen, or justifies mass surveillance.

Two, the report did not find that the resource costs, privacy impacts, and economic harms associated with bulk collection are balanced by any concrete benefits in intelligence capabilities. In fact, the report emphasizes that the policy and legal arguments that weigh in favor of ending mass surveillance programs are not at conflict with their conclusions.

Finally, the report acknowledges that there are additional steps that the intelligence community can take to increase transparency, improve oversight, and limit the use of information collected through surveillance.

Fundamentally, the surveillance question is about whether our country is willing to trade constitutional liberties for dragnet surveillance programs that have yet to prove their effectiveness.

And, unsurprisingly, there is no software solution to that debate.
