An arrest warrant is a judicial order supported by probable cause that permits the police to search, seize and arrest a criminal suspect
A warrant directs law enforcement to arrest or search a specific person or premises of a criminal suspect. If the search results in evidence, law enforcement may seize such evidence.
A warrant must be based on a sworn declaration establishing a specific factual basis in order to meet the constitutional 4th Amendment legal requirement of establishing “probable cause” that a crime was committed or is being planned or is in the process of being committed.
FISA Search Warrant
A “FISA Warrant” is a judicially sealed order to search, seize and/or arrest a suspect and which has been prepared and presented to a special FISA magistrate in secret permitting federal law enforcement to search and seize suspects that threaten the national security of the United States.
These types of warrants’ issuance have come under recent legal scrutiny under the Trump administration beginning in 2021.
