Frequently Asked Questions

What is the Fourth Amendment and how does it protect digital privacy?
The Fourth Amendment protects individuals against unreasonable searches and seizures. In the digital age, this extends to phone contents, cloud storage, location information, and metadata. The Supreme Court’s Carpenter v. United States decision established that accessing historical cell-site location information constitutes a search requiring a warrant. This framework applies to geofence warrants, phone searches, and cloud data access.
What is viewpoint discrimination and why does it matter for free speech?
Viewpoint discrimination occurs when government or other actors suppress speech based on the speaker’s perspective. The First Amendment strictly prohibits government viewpoint discrimination. The landmark case Chaker v. Crogan (9th Circuit, 2005) established that state statutes permitting viewpoint-based prosecution violate the First Amendment.
What is counter-forensics and how does it relate to privacy?
Counter-forensics refers to techniques used to prevent, detect, or defend against digital forensic examination. Examples include whole-disk encryption (BitLocker, VeraCrypt), secure file deletion, and hardware security modules. Forensic tools like EnCase, GrayKey, and Cellebrite can sometimes bypass device security. Counter-forensics strategies help defend against unauthorized access.
What is the Fifth Amendment protection for encryption?
The Fifth Amendment privilege against self-incrimination protects individuals from being compelled to produce encrypted data. Courts apply the forgone conclusion doctrine—if the government already knows specific files exist, compelled decryption may not violate the Fifth Amendment. Federal circuits remain split on this issue, and biometric unlocking raises distinct legal questions.
