Tales from the (Quantum) Crypt

The dream of hack-proof communication just got a little closer to reality. On August 16, 2016, China launched the world’s first “quantum satellite,” a project the Chinese government hopes will enable it to build a communication system incapable of being hacked. Such a system, if perfected, would allow for encrypted communications between any two devices … Continue Reading

California Gives the Fourth Amendment a 21st Century Makeover

The average American today generates more media than they did at any other point in history, and the ease with which our communications, photos, and videos are sent and stored digitally means most of us have more media stored in the cloud or on a single digital device than previous generations would have created in … Continue Reading

Supreme Court Invalidates Los Angeles Law Authorizing Warrantless Searches of Hotel Records

In City of Los Angeles v. Patel, the Supreme Court invalidated a Los Angeles law that allowed law enforcement officials to inspect hotel and motel guest registries at any time, without a warrant or administrative subpoena.

Landmark Supreme Court Ruling Protects Cell Phones from Warrantless Searches

On June 25, 2014, the Supreme Court unanimously ruled that police must first obtain a warrant before searching the cell phones of arrested individuals, except in “exigent circumstances.” Chief Justice John Roberts authored the opinion, which held that an individual’s Fourth Amendment right to privacy outweighs the interest of law enforcement in conducting searches of … Continue Reading

On Monday, the California Supreme Court ruled that the Fourth Amendment to the United States Constitution did not prohibit a deputy sheriff from conducting a warrantless, post-arrest search of the text messages of an arrestee. Specifically, the Court affirmed the decision of the Court of Appeal that the cell phone was “immediately associated with [defendant’s] person … Continue Reading

No Doubt No Reasonable Suspicion Required — Laptops Now Fair Game at the Border

My very first blog post addressed a precedent-setting decision of the Central District of California holding that federal agents could not conduct a border search of the private and personal information stored on a traveler's computer hard drive or electronic storage devices without reasonable suspicion. Eighteen months later, the Ninth Circuit has squarely reversed that decision. In a short opinion filed April 21, 2008, Judge O'Scannlain wrote in U.S. v. Arnold, No. 06-50581, that "reasonable suspicion is not needed for customs officials to search a laptop or other personal electronic storage devices at the border." As far as the Ninth Circuit is concerned, for purposes of border searches under the Fourth Amendment, laptops and other electronic storage devices are not so much like a home or the human mind - they are more akin to luggage or a car. … Continue Reading

Ninth Circuit Applies Pen Register and Mail Principles to Warrantless Monitoring of Internet Traffic

In a novel case, the Ninth Circuit ruled on July 6, as amended July 25, that government surveillance of Internet Protocol (“IP”) addresses visited, to/from addresses of emails, and the total volume of information sent to or from an email account does not violate the Fourth Amendment. United States v. Forrester, No. 05-50410, — F.3d — … Continue Reading

Expectation of Privacy in Student Computer Persists in the Absence of Announced Monitoring Policy

Last week, a panel of the Ninth Circuit Court of Appeals held that in the absence of an announced monitoring policy, the mere act of connecting a computer to a network does not extinguish a user’s reasonable expectation of privacy, under the Fourth Amendment, in the contents of his or her computer. The panel announced its … Continue Reading
