Which scenario does NOT justify a warrantless search according to the discussed cases?

A scenario involving a vehicle parked in a private garage does not justify a warrantless search because individuals have a reasonable expectation of privacy in their homes and private garages. The law generally protects the sanctity of private property, making it imperative for law enforcement to obtain a warrant before searching such premises unless there are exceptional circumstances.

In contrast, scenarios that involve public safety concerns, exigent circumstances, or an arrest made at the scene typically allow for warrantless searches. For instance, during a traffic stop, officers may act swiftly if they perceive a threat to public safety. Similarly, exigent circumstances might arise when there is an immediate need to prevent the destruction of evidence or protect life. Lastly, if an arrest has been made at the scene and evidence is in plain view or easily accessible in a vehicle, officers can conduct a search without a warrant under the assumption that evidence may be lost if they were to wait until a warrant was obtained. Hence, the particular conditions surrounding public areas and the immediate need for law enforcement action create scenarios where a warrant is not necessary, contrasting sharply with the rights afforded to private property.
