Which statement best describes custodial interrogation?

• A. The voluntary interview conducted with no restraint
• B. Any police questioning conducted without a warrant
• C. The suspect's freedom of movement is restrained and they are questioned to elicit self-incriminating statements
• D. A casual conversation with no police influence

Answer: (C)

Custodial interrogation occurs when the person’s freedom of movement is restrained and they are questioned to elicit self-incriminating statements. The key here is both elements: restraint of liberty (the person is not free to leave or is under police control) and an investigative purpose aimed at obtaining admissions. This combination is what makes the questioning custodial and triggers the need for warnings and waivers (Miranda) before questioning. In non-custodial situations—such as casual talks or interviews where the person can leave—the warnings aren’t required, and the interaction isn’t considered custodial interrogation.
