As a threshold matter, Congress could clearly let Section 702 sunset and return the law to the position that existed before 2008. We are, once again, looking at a reauthorization after years of open defiance and violations by the government. Allowing the sunsetting of this provision would establish a clear deterrent for the agencies under an “abuse it, lose it” rationale. However, in the absence of such a decision, there are other areas worth exploring for needed reforms.

Louis Brandeis famously described privacy as “the right to be let alone,” an essential human component.2 These warrantless searches discussed below threaten a host of rights including free speech, the free press, freedom of religion, and free association. Such surveillance creates a chilling effect on citizens exercising their rights, particularly free speech, when they are uncertain whether the government is collecting and storing their communications.
