Which concept justifies a peace officer's entry into a home if they have been denied permission after showing authority?

The concept that justifies a peace officer's entry into a home after being denied permission, particularly when they have shown authority, is the principle of hot pursuit. This legal doctrine allows officers to pursue a suspect who is fleeing into a residence if they have probable cause to believe that person has committed a crime. In hot pursuit scenarios, immediate action is often necessary to prevent the destruction of evidence or to apprehend a suspect, making it legally justifiable for officers to enter a home without a warrant.

This principle emphasizes the need for swift action in law enforcement situations where waiting to obtain a warrant could compromise public safety or the integrity of an investigation. It recognizes that in certain urgent circumstances, traditional legal protocols may be set aside to protect life and enforce the law. In contrast, other concepts like the warrant requirement and consent to entry do not apply because they establish conditions under which entry is permissible; while the emergency exception could be relevant in certain situations, it specifically pertains to exigent circumstances that require immediate intervention.
