What is required for a constitutionally valid search?

• A. Consent from the suspect.
• B. Probable cause alone without warrant.
• C. A valid warrant or a recognized exception.
• D. Only a search incident to arrest is valid.

Answer: (C)

The main idea is that a search is constitutionally valid only if the police either have a valid warrant supported by probable cause and particularity, or fall within a recognized exception to the warrant requirement. A warrant pairs probable cause with specificity about where to search and what to seize. If no warrant exists, a valid exception must apply, such as voluntary consent given by someone with authority, a search incident to a lawful arrest, exigent circumstances, the automobile exception, plain view, etc. Probable cause alone, without a warrant or an applicable exception, is not sufficient for a general search. Likewise, a search incident to arrest is just one of several exceptions, not the only valid route. So the correct rule is that a constitutionally valid search requires either a valid warrant or a recognized exception to the warrant requirement.
