Answer :
Final answer:
A search warrant primarily requires probable cause, a standard set by the Fourth Amendment, which reflects a reasonable belief of criminal activity or the presence of evidence.
Explanation:
The primary requirement for a search warrant is probable cause. According to the Fourth Amendment, no warrants shall issue without probable cause, which must be supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. Probable cause is a higher standard than reasonable suspicion and denotes a reasonable belief that a person has committed a crime or that evidence of a crime will be found in the place to be searched.
