Key Areas of Police Case Law
This cheat sheet focuses on several core areas frequently encountered in police work. Understanding these areas is crucial for maintaining legal compliance.
Search and Seizure
-
Mapp v. Ohio (1961): Established the Exclusionary Rule, preventing the admission of illegally obtained evidence in state criminal trials. This is crucial for the admissibility of evidence collected by law enforcement. Understanding the specifics of the Exclusionary Rule is paramount.
-
Terry v. Ohio (1968): Allows for "stop and frisk" searches based on reasonable suspicion, a lower standard than probable cause. The officer must have specific and articulable facts to justify the stop and the frisk. This case significantly shaped the practice of investigative stops.
-
Arizona v. Gant (2009): Limits the scope of vehicle searches incident to arrest to the area within the immediate control of the arrestee and where evidence of the crime of arrest might be found. This case clarifies the permissible scope of a search during an arrest.
-
Carroll v. United States (1925): Establishes the automobile exception to the warrant requirement, allowing searches of vehicles without a warrant if there is probable cause to believe they contain contraband or evidence of a crime. This case is frequently used to justify searches of vehicles.
Interrogations and Confessions
-
Miranda v. Arizona (1966): Requires law enforcement officers to inform suspects of their rights during custodial interrogations, including the right to remain silent and the right to an attorney. Knowing and accurately applying Miranda warnings is vital.
-
Dickerson v. United States (2000): Affirmed the constitutionality of Miranda v. Arizona, stating that Congress cannot legislatively overrule Miranda. This case reinforces the importance of Miranda rights.
-
Edwards v. Arizona (1981): Once a suspect invokes their right to counsel, questioning must cease until counsel is present. This protects a suspect's right to legal representation.
Use of Force
- Graham v. Connor (1989): Established the "objective reasonableness" standard for evaluating police use of force, considering the facts and circumstances known to the officer at the time. This is a pivotal case for understanding the legal justification for the use of force.
Other Important Cases:
Many other cases refine and clarify these core areas. Regular review of updated case law is essential for staying current in police procedures.

You have the right to remain silent and the right to an attorney. If you are arrested, you must be informed of your Miranda rights.
