In which scenario is a police officer allowed to conduct a search of a residence without a warrant?

A police officer can conduct a search of a residence without a warrant in multiple circumstances, and each scenario presented reflects established legal principles regarding warrantless searches.

When a resident gives verbal consent, that consent provides the officer with the authority to search the premises legally. The key aspect is that the consent must be given voluntarily and not coerced.

In cases where the police are executing an arrest warrant, if there is reasonable belief that the suspect is located within the residence, they can enter and search for that individual. This is part of the officer's authority to ensure the arrest is made safely and effectively.

Additionally, law enforcement may conduct a warrantless search if they have probable cause to believe that evidence is being destroyed or that evidence may be lost. This exception to the warrant requirement is in place to prevent the destruction of significant evidence that may be crucial for a case.

These scenarios collectively illustrate distinct exceptions to the warrant requirement, affirming that a police officer is indeed permitted to search a residence without a warrant under all of these conditions.
