We Need to Stop Warrantless Spying on Americans. Here's How.

We disagree on many issues. One of us is a longtime Democrat, the other a conservative Republican. But both of us are deeply concerned about warrantless government surveillance of the American people.

In 2008, Congress enacted Section 702 of the Foreign Intelligence Surveillance Act to allow the government to gather vital intelligence about foreign governments, terrorists and spies. The problem is that it has also allowed agencies like the F.B.I. and the National Security Agency to regularly gather and search through the private communications of American citizens without a warrant. That is a clear violation of rights protected by the Constitution.

It's true that Section 702 doesn't allow the direct targeting of Americans, but their communications are still often gathered during the warrantless surveillance of foreigners abroad. Once the government has this data, agencies then have the ability to search through it. And they do: Transparency reports reveal that thousands of such searches are performed every year. A federal court previously found that some the F.B.I. had conducted had violated the Fourth Amendment.
