Miranda Interrogation

For officers and detectives, Illinois v. Perkins means that Miranda warnings are not required simply because a suspect is in jail if the suspect does not know he is talking to law enforcement. An undercover officer or agent posing as an inmate may speak with an incarcerated suspect, and the suspect’s statements are not excluded under Miranda solely because no warnings were given.

For officers and detectives, Davis v. United States creates an important distinction between a clear request for a lawyer and an uncertain comment about a lawyer. If a suspect says something direct like “I want a lawyer,” “I want an attorney,” or “I will not talk without a lawyer,” questioning must stop unless counsel is provided or the suspect later reinitiates communication under the applicable rules.

Stansbury v. California is a reminder that Miranda custody is judged from the outside, not from inside the officer’s head. What matters is what a reasonable person in the interviewee’s position would understand from the circumstances.

Patterson v. United States: for police officers, Patterson is a cautionary case rather than a green light. The Supreme Court did not say that physical evidence found after Miranda-defective questioning is automatically usable.

Pennsylvania v. Bruder reinforces that officers generally may conduct ordinary roadside DUI investigations without first giving Miranda warnings. During a typical traffic stop, an officer may make observations, request license and registration, ask basic investigative questions, and continue the roadside investigation without automatically converting the encounter into Miranda custody.

For officers and detectives, Thompson v. Keohane, Warden, et al. reinforces that Miranda custody is not controlled by labels alone.

Dickerson v. United States confirms that officers should continue treating Miranda as a constitutional requirement during custodial interrogation. If a suspect is in custody and officers want to ask questions reasonably likely to produce incriminating responses, the safer and legally required practice is to give the Miranda warnings before questioning.

McKune v. Lile: mcKune, Warden, et al. v. Lile does not give officers a general license to pressure inmates or suspects into confessing.

For officers and detectives, Montejo v. Louisiana means that appointment of counsel after a first court appearance does not always prohibit police from initiating a later custodial interview. If the suspect is properly Mirandized and chooses to waive those rights, the Sixth Amendment does not automatically suppress the statement merely because counsel has been appointed.

Kansas v. Ventris should not be read as permission to place informants near charged defendants for the purpose of getting around defense counsel. Once formal charges have been filed and the Sixth Amendment right to counsel has attached, officers and agents must not deliberately elicit statements from the accused outside the presence of counsel or without a valid waiver.

Kaupp v. Texas is a warning that “bringing someone in for questioning” can legally become an arrest based on what officers do, not what they call it. If officers wake a suspect at home, control his movement, handcuff him, place him in a patrol car, and transport him to another location, a court is very likely to view that as an arrest.

For federal officers, and for state or local officers working closely with federal agents, Corley v. United States is a reminder that Miranda warnings are not the only timing concern during interrogation. Advising a suspect of rights and obtaining a waiver are important, but they do not automatically solve a prompt-presentment problem.

Davis v. Washington matters because it affects how courts view statements gathered during emergency calls and on-scene domestic violence investigations. When officers or dispatchers are trying to determine whether there is an immediate threat, where the suspect is, whether anyone is injured, and what response is needed, the resulting statements are more likely to be viewed as non-testimonial.

Yarborough v. Alvarado: yarborough, Warden v. Alvarado is a reminder that a station-house interview is not automatically “custody” for Miranda purposes. If a person voluntarily comes to the station, is not restrained, is not threatened with arrest, and leaves afterward, those facts can support a finding that Miranda warnings were not required.

For officers and detectives, Salinas v. Texas matters most during voluntary, noncustodial interviews. If a person is not in custody and voluntarily speaks with police, the Constitution does not automatically bar the government from later using the person’s selective silence in response to a question, at least where the person did not clearly invoke the Fifth Amendment.

Fellers v. United States is an important reminder that Miranda and the Sixth Amendment are related but not identical. Miranda focuses on custodial interrogation.

Texas v. Cobb is important for officers and detectives because it confirms that the Sixth Amendment right to counsel is offense-specific. If a person has been charged and has counsel on one offense, that does not automatically prevent officers from questioning the person about a separate, uncharged offense.

For officers, Bridgers v. Texas is a reminder that Miranda wording matters. A warning that starts correctly with “You have the right to remain silent” is only part of the requirement.

For officers and detectives, J. D. B. v. North Carolina means that juvenile interviews require careful custody analysis before questioning begins. If the subject is a child, especially a young teenager, officers should not evaluate the situation exactly as if the subject were an adult.

For police officers, Missouri v. Seibert is a warning against using Miranda as an afterthought. If a suspect is in custody and officers are going to interrogate, Miranda warnings should be given before questioning begins.

For police officers and detectives, Florida v. Powell confirms that courts look at the Miranda warning as a whole. A warning does not automatically fail just because it uses wording different from the standard Miranda phrasing.

Bobby v. Dixon: for officers and detectives, Bobby, Warden v. Dixon reinforces a basic point: Miranda warnings are required before custodial interrogation. If a person is not in custody, Miranda warnings are not constitutionally required, although giving clear advisements may still be the safer practice in serious investigations.

United States v. Patane does not give officers permission to ignore Miranda. Officers should still give complete Miranda warnings before custodial interrogation when they want to question a suspect and preserve the suspect’s statements for use in court.

For police officers and detectives, Maryland v. Shatzer is an important Miranda case because it gives a concrete time rule. If a suspect in custodial interrogation asks for a lawyer, stop questioning immediately.

Howes v. Fields: howes, Warden v. Fields is important for officers and detectives who interview inmates about crimes that are separate from the sentence the inmate is already serving. The case teaches that an inmate is not automatically in Miranda custody just because officers remove him from his cell or housing unit and question him in another room about an outside offense.

Vega v. Tekoh does not eliminate Miranda. Officers still need to understand and follow Miranda when conducting custodial interrogation.

In Miranda v. Arizona, the Supreme Court held that statements from custodial interrogation generally cannot be used unless law enforcement first provides warnings protecting the privilege against self-incrimination and the right to counsel, and any waiver is voluntary, knowing, and intelligent.

Edwards v. Arizona held that once a person in custody invokes the Miranda right to counsel, police cannot initiate further custodial interrogation unless counsel is provided or the person initiates further communication and validly waives the right.

In Berghuis v. Thompkins, the Supreme Court held that a suspect who has received and understood Miranda warnings must clearly invoke the right to remain silent. Remaining mostly silent during an interrogation does not, by itself, require police to stop questioning, and an uncoerced answer can amount to an implied waiver.
