Learning Objective: Do you know what is required for an effective search? To conduct an effective search, know the legal requirements for searching, the items being searched for and the elements of the crime being investigated; be organized, systematic and thorough.
- Learning Objective: Do you know what basic restriction is placed on all searches? The most important limitation on any search is that the scope must be narrow. General searches are unconstitutional.
- Learning Objective: Do you know what the exclusionary rule is and how it affects investigators? The exclusionary rule established that courts may not accept evidence obtained by unreasonable search and seizure, regardless of its relevance to a case. Weeks v. United States (1914) made the rule applicable at the federal level; Mapp v. Ohio (1961) made it applicable to all courts.
- Learning Objective: Do you know what the preconditions and limitations of a legal search are? A search can be justified and therefore considered legal if any of the following conditions are met: A search warrant has been issued. Consent is given. An officer stops a suspicious person and believes the person may be armed. The search is incidental to a lawful arrest. An emergency exists. Also, a search conducted with a warrant must be limited to the specific area and specific items named in the warrant, in accordance with the particularity requirement (Stanford v. Texas, 1965).
- Learning Objective: Do you know what the preconditions and limitations of a legal search are? Consent to search must be voluntary, and the search must be limited to the area for which consent is given.
- Learning Objective: Do you know what the preconditions and limitations of a legal search are? The Terry decision established that a patdown or frisk is a “protective search for weapons” and as such must be “confined to a scope reasonably designed to discover guns, knives, clubs and other hidden instruments for the assault of a police officer or others.”
- Learning Objective: Do you know what the preconditions and limitations of a legal search are? The Chimel decision established that a search incidental to a lawful arrest must be made simultaneously with the arrest and must be confined to the area within the suspect’s immediate control.
- Learning Objective: Do you know when a warrantless search is justified? A warrantless search in the absence of a lawful arrest or consent is justified only in emergencies or exigent circumstances where probable cause exists and the search must be conducted immediately (New York v. Quarles, 1984).
- Learning Objective: Do you know what precedents are established by the Weeks, Mapp, Terry, Chimel, Carroll and Chambers decisions? Carroll: Established that automobiles may be searched without a warrant if (1) there is probable cause for the search and (2) the vehicle would be gone before a search warrant could be obtained. Chambers v. Maroney (1970): Established that a vehicle may be taken to headquarters to be searched. Chimel: Established that a search incidental to a lawful arrest must be made simultaneously with the arrest and must be confined to the area within the suspect’s immediate control. Weeks and Mapp: The exclusionary rule established that courts may not accept evidence obtained by unreasonable search and seizure, regardless of its relevance to a case. Weeks v. United States (1914) made the rule applicable at the federal level; Mapp v. Ohio (1961) made it applicable to all courts. Terry: Established that a patdown or frisk is a “protective search for weapons” and as such must be “confined to a scope reasonably designed to discover guns, knives, clubs and other hidden instruments for the assault of a police officer or others.”

- Learning Objective: Do you know what search patterns are used in interior searches? Interior searches go from the general to the specific, usually in a circular pattern, covering all surfaces of a search area. The floor should be searched first.
- Learning Objective: Do you know whether evidence left in plain view may be lawfully seized and whether it is admissible in court? Plain-view evidence—unconcealed evidence seen by an officer engaged in a lawful activity—is admissible in court.
- Learning Objective: Do you know how to search a vehicle? Remove occupants from the car. First, search the area around the vehicle, and then the exterior. Finally, search the interior along one side from front to back, and then return along the other side to the front.
- Learning Objective: Do you know how to search a suspect? If the suspect has not been arrested, confine your search to a patdown or frisk for weapons. If the suspect has been arrested, make a complete body search for weapons and evidence. In either event, always be on your guard.
