What must an officer demonstrate to arrest someone at another's home?

An officer must demonstrate a search warrant for the residence or show exigent circumstances to lawfully arrest someone at another person's home. A search warrant is a legal document issued by a judge or magistrate, granting law enforcement the authority to enter a specific location to search for evidence of a crime and make arrests. This protects the Fourth Amendment rights against unreasonable searches and seizures.

Exigent circumstances, on the other hand, allow officers to enter a property without a warrant if there is an immediate need, such as preventing the destruction of evidence, pursuing a fleeing suspect, or addressing a situation that poses a danger to life or risk of serious injury. Both scenarios align with legal standards that uphold individuals' rights while allowing officers to perform their duties effectively and safely.
