The NSA has justified their surveillance programs by presenting the number of terrorist activities these programs disrupted. This paper finds this method of measuring the effectiveness of surveillance technology by counting successful cases to be not enough. It is only one measure of assessing effectiveness and should not be used in isolation to determine a technology's effectiveness.
