Fourth Amendment Warrant

Requires a warrant based on probable cause to search, part of American legal protection against unreasonable searches.

Reasonable suspicion

Particularity (in warrants)

Warrants must be specific, not general, outlining the exact place and items sought (what is searched, where, and what is looked for).

Evidence Seizure Balance

Weighing public interest against individual privacy rights when seizing evidence, especially digital data. Intermingled of personal and potential evidence is a problem.

Study Notes

  • The first ten Amendments were created to counter the perceived tyranny of the English legal system.
  • These Amendments are a part of the system of checks and balances in the American government, including federal, state and local governments.
  • The Fourth Amendment (4A) requires probable cause and a warrant for searches.

Reasonable Suspicion

  • Officers can stop someone for investigation with reasonable suspicion.
  • During the stop, officers can conduct a limited pat-down search for weapons.

Warranted Searches and Computers

  • Warrants must be specific. Interpretations of specificity vary by court.
  • Searches must balance public interest and individual's right to privacy.
  • Intermingled personal and potentially incriminating evidence can complicate searches.
  • Valid searches of storage devices require mentioning of the devices in the original warrant. (U.S. v. Ross, 1992)

Third-Party Origination

  • The Fourth Amendment does not apply to third parties acting under law enforcement direction.

Other Arguments in Warranted Searches

  • A warrant becomes stale when not executed in a timely manner. (U.S. v. Hay)

Warrantless Searches

  • Consent for searches must be reasonable.
  • The totality of circumstances regarding physical access and control must be considered for validity.

Exigent Circumstances

  • Factors in exigent circumstances: degree of urgency, time to obtain a warrant, volatility of evidence, danger at site, suspect's knowledge of imminent police action, and risk of contraband destruction.

Incident to Arrest

  • Searches incident to arrest are for safety and to inventory items on the arrestee.
  • Computers, laptops, and PDAs are not normally searched incident to arrest.

Plain View

  • Visible evidence does not require a warrant, but only if it is visible.
  • (U.S. v. Carey) If an item is discovered while executing a valid warrant, the search is valid.

Border Searches

  • Border searches do not require probable cause.

Other Warrantless Searches

  • Auto searches, field interrogations, and inventory searches are not typically related to computers.

Electronic Surveillance and the Right to Privacy

  • Recognized types of privacy include physical, communication, and information.
  • Territorial privacy is challenging to define in cyberspace.

Private vs. Public Sector Searches

  • In private sector searches, expectation of privacy is evaluated regarding:

    • Whether items or areas are for exclusive use.
    • Employee permission to store items and/or information.
    • Employee notification that the system may be accessed by others.

  • Considerations: history of searches, a clearly defined policy regarding common/private areas.

Application of Ortega to Email

  • Government system administrators have the right to monitor their systems for duties, including routine protection monitoring, system management, unauthorized access prevention, and security procedure verification.
  • Law enforcement monitoring requires consent, court order/warrant, or probable cause.
  • System administrators do not work under law enforcement direction unless for the uncovery of evidence.

Privacy Protection Act of 1980

  • Local, state, or federal authorities cannot search records or seize publishable materials without probable cause.
  • This law has been criticized for vagueness, ambiguity, and overbreadth.
  • Possible victims of the act include publishers, authors, editors, newspapers, and those disseminating information.

Communications Assistance for Law Enforcement Act (CALEA)

  • Manufacturers and service providers must create systems with surveillance capabilities for telephones, cellular systems, advanced paging, satellite-based systems, and specialized mobile radio.

Other Questions Regarding Privacy

  • Peer-to-peer or file sharing unclear regarding reasonable expectation of privacy.
  • Internet Service Provider (ISP) subscriber records unlikely to have a reasonable expectation of privacy regarding basic subscriber info.
  • No expectation of privacy regarding posted material on the internet.
  • Cell phones differ from landlines regarding reasonable expectation of privacy. Exigent circumstances may allow for warrantless searches.
