In the majority opinion for the unanimous Court in Riley v. California (2014), Chief Justice John Roberts wrote, “The fact that technology now allows an individual to carry such information in his hand does not make the information any less worthy of the protection for which the Founders fought.” This “go get a warrant” sentiment is echoed again and again in more recent cases involving cell phone privacy. By taking a closer look at how exactly a search warrant works, it becomes increasingly clear that this protection is needed now more than ever as we enter the digital age.

A federal judge in New York ruled for the first time on Tuesday that the use of a surveillance device to capture cell phone location information constitutes a warrantless search. In the case, Lambis v. United States, government officials used a stingray device to track a drug suspect. Stingrays, also known as “cell site simulators,” force cell phones in the area to transmit signals that pinpoint the user’s location through cell site location information, or CSLI data.

The fight over NSA surveillance is about to heat up again. This week, the House will consider a measure that would require the NSA and other government agencies to follow due process and obtain a warrant to collect the communications of American citizens. Through an amendment to H.R. 5293, the Department of Defense Appropriations Act of 2017, the House could defund warrantless government searches of the database of information collected under Section 702 of the Foreign Intelligence Surveillance Act (FISA).

This week, the House will consider a bill that would stop the Internal Revenue Service (IRS) from collecting identifying information about donors to tax-exempt organizations. The IRS, in repeatedly using tax disclosures to create political targets, has prompted a chilling effect on First Amendment rights and political free speech.
