Which situation allows for a warrantless search of a person?

The correct choice highlights two important concepts that justify a warrantless search: consent and exigent circumstances.

When a person gives consent, law enforcement can search without a warrant because the individual has voluntarily waived their Fourth Amendment rights against unreasonable searches and seizures. This means that if someone agrees to a search, law enforcement can proceed without needing to obtain a warrant.

Exigent circumstances refer to situations where there is an urgent need for action that makes obtaining a warrant impractical. This can occur if there is a risk that evidence might be destroyed or if there is an immediate danger to life or safety. In such cases, law enforcement can act swiftly to prevent harm or secure evidence without the delay of seeking a warrant.

The other options do not meet the legal requirements needed for warrantless searches. For instance, community events and favorable weather conditions do not create a legal basis for bypassing a warrant, nor does incomplete paperwork provide any justification for such actions. Only through consent or the presence of exigent circumstances can police lawfully conduct a search without a warrant.
