Fourth Amendment

“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” 

- U.S. Const. amend. IV. 

NACDL seeks to ensure that the Fourth Amendment remains a vibrant protection against encroachments on the privacy of the individual through litigation and public advocacy. The Fourth Amendment is the appropriate starting point for assessing the limits on government intrusion into one’s privacy, and its protections must continue to thrive in the digital age. The Fourth Amendment and its guarantees should not turn on the medium used to transmit private information, nor on how the information is stored. NACDL strives to guarantee that evidence obtained in violation of the Fourth Amendment is excluded in a court of law.

Encryption Webinar

NACDL Webinar 3-29-2016 - Keep It Confidential: Protecting Your Privileged Client Communications with Encryption 

Defense lawyers regularly use phone calls, texts, and emails to communicate with clients, investigators, witnesses and others associated with their cases. Many of these communications are privileged, yet government surveillance programs can capture and store them. This webinar explored how this happens, and how defense lawyers can keep their communications out of government hands.

During the first part of the webinar, Jack Gillum, reporter on The Associated Press's Washington investigations team, addressed his experience with encrypting communications and why he and others in his industry have made the switch to these encrypted platforms. Neema Singh Guliani, Legislative Counsel at the American Civil Liberties Union, then laid out the different surveillance programs and technologies that may be intercepting your privileged communications. Video recording of this first part of the webinar is available here.

During the second part of the webinar, Harlo Holmes, Digital Security Trainer with the Freedom of the Press Foundation, walked through some basic ways to encrypt phone calls, texts, and email communications. Video recording of the second part of the webinar is available here.
