Final answer:
An arrest warrant typically requires consent or exigent circumstances to enter a home, but exceptions like 'hot pursuit' exist. The Fourth Amendment and court rulings such as Georgia v. Randolph protect against unreasonable searches, with limited exceptions.
Step-by-step explanation:
An arrest warrant alone typically does not authorize police to enter a home without consent or exigent circumstances. The Fourth Amendment protects citizens from unreasonable searches and seizures, requiring that a warrant be supported by probable cause and a detailed description of the place to be searched and the persons or things to be seized. However, a notable exception occurs when there's a hot pursuit of a fleeing felon, where officers may pursue the suspect into a private residence without a warrant or the resident's consent.
In cases like Georgia v. Randolph, the Supreme Court has held that police cannot conduct a warrantless search in a home where one occupant consents and the other objects. Additionally, under the exclusionary rule, evidence obtained without adhering to legal procedures can be suppressed, but this rule has exceptions, such as the good faith exception and the inevitable discovery doctrine.
