Study Notes
Fourth Amendment and Legal Issues in Computer Forensics
- The first ten amendments were created in response to perceived tyranny of the English system, serving as checks and balances in the US system (Federal government, states, and divisions of authority).
- The Fourth Amendment (4A) requires probable cause and a warrant for searches.
- Probable cause is a legal standard requiring specific and trustworthy information to reasonably believe a crime has/is being committed.
Reasonable Suspicion and Limited Searches
- Officers can stop individuals with reasonable suspicion to investigate, but only with that suspicion.
- A limited "pat-down" search for weapons is allowed during a justifiable stop.
Warranted Searches and Computers
- Search warrants must be specific (particularity) about the items or locations to be searched. This is subject to interpretation by courts.
- Seizing evidence balances public interest with individual rights and security, and can be complex with intermingled personal and potentially incriminating materials.
- Valid searches of storage devices need to be explicitly and accurately documented in the warrant to be considered valid (ex. U.S. v. Ross, 1992).
- Third-party origination (e.g., evidence from a third party) is not covered by the Fourth Amendment unless the third party is acting under direct law enforcement supervision.
Staleness as a Search Argument
- Staleness is the argument that a warrant was not sought promptly. A warrant might be invalidated.
Warrantless Searches
- Consent: Must be reasonable in scope and circumstances are crucial to determining its validity. Physical control and limited access are important considerations.
- Exigent Circumstances/Emergency: In emergency situations, law enforcement must balance urgency against the need for obtaining a warrant (urgency degree, time needed to apply for warrant, volatility of evidence, danger at the scene, suspect's knowledge of imminent action, and risk of contraband destruction.)
- Incident to Arrest: Searches are for safety reasons and limited to the area under the arrestee's immediate control (does not include PCs, laptops, or PDAs).
- Plain View: There is no violation of privacy if items are in plain view; this only applies to visible items. If an item is first observed during a warranted search, it is valid. (ex. U.S. v. Carey)
- Border Searches: Probable cause is not always required for border searches.
Electronic Surveillance and the Right to Privacy
- Recognized privacy types: physical, communication, and informational. Geographical privacy is most challenging to define in cyberspace scenarios.
Private vs. Public-Sector Searches
- Evaluating expectation of privacy for private-sector searches considers factors like designated areas, use permission from employees, and if access by others has been communicated beforehand.
- Existing history of searches or inspections and whether a clearly defined policy exists on dividing public and private areas are factors for evaluation.
Application of Ortega to Email
- System administrators have the right to monitor government equipment within their job scope. Routine monitoring for security, systems management, verifying security procedures, and ensuring system survivability and operational security are part of their authority.
- Law enforcement monitoring requires consent of one party, court authority, or the demonstration of probable cause.
- System administrators cannot work under law enforcement direction to uncover evidence.
Privacy Protection Act
• Local, state, or federal authorities cannot seize publishable material without probable cause.
Criticism of Electronic Communications Privacy Act (ECPA) and the Privacy Protection Act of 1980
- ECPA, and the 1980 act were criticized for ambiguity and broad interpretation.
- Publications, authors, editors, newspapers, and anyone disseminating information are potential victims.
Communications Assistance for Law Enforcement Act (CALEA)
- The CALEA law mandated telecommunications equipment manufacturers and providers to develop systems capable of monitoring telephone, cellular, advanced paging, satellite-based systems, and mobile radio communications.
Other Privacy Questions
- File sharing and peer-to-peer networks raise privacy issues regarding the reasonable expectation of privacy.
- Internet service providers' subscriber records might not enjoy a reasonable expectation of privacy.
- Websites, in contrast, offer little to no expectation of privacy for posted content.
- Exigent circumstances can justify warrantless searches of cell phones; however, courts have exhibited inconsistencies in their applications.
- Court policies on selecting the location of a trial, methods used in undercover investigations, and the implications of sentencing guidelines involving child pornography are unclear.
Conclusions
- There is a need for greater guidance from the Supreme Court and Congress regarding expectations of privacy in the growing convergence of technology and especially issues of privacy as it relates to physicality.
