Which elements are necessary for issuing a search warrant?

The correct answer highlights the necessity of a statement of probable cause and a supporting oath when issuing a search warrant. A search warrant must be grounded in probable cause, which essentially means there is a reasonable basis to believe that a crime has been, is being, or will be committed, and that evidence of the crime can be found at the specified location. Additionally, this probable cause must be supported by a sworn affidavit, where the officer provides the facts and circumstances that lead to this belief. This procedure ensures that the issuance of search warrants is legally justified and protects citizens' rights against unreasonable searches and seizures.

The other options, while relevant to law enforcement practices, do not fulfill the necessary criteria for obtaining a search warrant. Understanding of case law is certainly important for ensuring compliance with legal standards, and the presence of an officer can be essential during the execution of a warrant, but neither is a fundamental requirement for obtaining one. Likewise, while a victim's consent may sometimes facilitate a search, it is not a necessary element for issuing a warrant, as warrants can still be sought regardless of consent if probable cause is established.
