Step-by-step explanation:
A search warrant may be executed when a judge issues the warrant based on probable cause. The Fourth Amendment to the United States Constitution protects against unreasonable searches and seizures and requires that warrants be supported by oath or affirmation and particularly describe the place to be searched and the items to be seized. In some situations, however, a search warrant may not be necessary, such as when the owner or renter consents to the search or if there are exigent circumstances.
