Warrant: A warrant is a legal document issued by a judge that authorizes law enforcement to conduct a search or make an arrest. It must be based on probable cause, which means there is sufficient evidence of wrongdoing.
Exclusionary Rule: The exclusionary rule is a legal principle that prohibits the use of evidence obtained through an illegal search or seizure in criminal proceedings. It serves as a deterrent against law enforcement misconduct.
Probable Cause: Probable cause refers to the reasonable belief that a crime has been committed and that the person being searched or arrested is involved in it. It is necessary for obtaining a warrant or justifying certain searches without one.
