In which situation can an officer restrict access to a property?

An officer can restrict access to a property as part of an ongoing investigation with exigent circumstances because this situation often requires immediate action to prevent the destruction of evidence, protect individuals at risk, or apprehend a suspect who may be fleeing. Exigent circumstances are defined by the need for swift action when there is no time to obtain a warrant; therefore, law enforcement has the authority to control access to a location to effectively address these urgent matters. This action is justified under the Fourth Amendment, allowing officers to ensure the integrity of the investigation and uphold public safety.

In contrast, while a property owner requesting assistance might lead to temporary access restrictions, it does not inherently give police the authority to restrict access broadly. The potential for hazards or routine checks lacks the immediacy required for exigent circumstances and would typically not justify restricting access.
