Which of the following is NOT a common exception to the warrant requirement?

• A. Consent
• B. Probable cause
• C. Plain view
• D. Exigent circumstances

Answer: (B)

Understanding the warrant requirement means recognizing when a search or seizure can happen without a warrant. Classic exceptions include consent (when someone with authority voluntarily allows the search), plain view (evidence in plain sight while lawfully present can be seized), and exigent circumstances (urgent situations like imminent danger or risk of destruction of evidence that require immediate action).

Probable cause, however, is not an exception by itself. It’s the level of belief needed to justify a warrant or certain warrantless actions; it’s the standard used to determine whether a warrant should be issued. It doesn’t automatically waive the need for a warrant on its own. So while consent, plain view, and exigent circumstances allow warrantless searches under specific conditions, probable cause serves as the basis for obtaining a warrant or for deciding when exceptions apply, not a standalone exception.
