What's at Stake
Our Constitution, laws, and values are the foundation of our strength and security. Yet, after the attacks of September 11, 2001, our government engaged in systematic policies of torture, targeted killing, indefinite detention, mass surveillance, and religious discrimination. It violated the law, eroded many of our most cherished values, and made us less free and less safe.
Some of these policies, such as torture and extraordinary rendition, are no longer officially condoned. But most other policies—indefinite detention, targeted killing, trial by military commissions, warrantless surveillance, and racial, religious, and other forms of profiling—remain core elements of U.S. national security strategy today.
Through litigation and advocacy strategies, the National Security Project responds to specific government measures and also strives to educate the public and shape the law so that the courts, Congress, and citizenry can serve as an enduring check against abuse. We work to ensure that the U.S. government renounces policies and practices that disregard due process, enshrine discrimination, and turn everyone into a suspect. We also seek accountability and redress for the victims of abuses perpetrated in the name of our national security. These are the ways to rebuild American moral authority and credibility both at home and abroad.
