Under what circumstance can an interrogation be deemed legal?

An interrogation can be deemed legal when the suspect is informed of their rights, which typically includes the rights to remain silent and to have an attorney present. This principle is rooted in the Miranda rights established by the U.S. Supreme Court, which aim to protect an individual’s Fifth Amendment rights against self-incrimination. When law enforcement informs a suspect of these rights prior to questioning, it ensures that the individual understands their legal protections and can make an informed decision about whether to speak with law enforcement. This step is crucial because, without it, any statements made during an interrogation could be inadmissible in court, as they may have been obtained in violation of the suspect’s rights.

In contrast, conducting an interrogation without a suspect's consent or in a public space does not typically meet the legal thresholds established for a valid interrogation. Similarly, not formally charging a suspect does not negate the need for rights advisement during the interrogation process.
