Which statement best describes probable cause and the warrant requirement?

• A. Probable cause exists only when there is certainty that a crime has occurred
• B. Warrants may be issued without any description of place if there is probable cause
• C. An oath or affirmation is unnecessary for warrants
• D. Warrants must describe with particularity and be supported by oath or affirmation; probable cause must exist

Answer: (D)

The rule being tested is that a valid search warrant must be grounded in probable cause, issued by a judge or magistrate upon an oath or affirmation, and describe with particularity the place to be searched and the items to be seized. Probable cause is a practical, not absolute, standard: there must be a reasonable belief that evidence or contraband is located in the place to be searched, not a certainty. The oath or affirmation provides the factual basis for that probable cause to the issuing authority. The description must be particular, so the warrant limits the search to the specified location and items, preventing a broad or exploratory rummage.

That protects against overbroad or abusive searches. A statement that probable cause requires certainty over belief is incorrect. A claim that a warrant can be issued without describing the place is incorrect because specificity is mandatory. A claim that an oath is unnecessary is incorrect because the oath or affirmation is a required part of issuing warrants. The described rule—warrants must describe with particularity, be supported by oath or affirmation, and rest on probable cause—is the correct understanding.
