What is the consequence of a suspect making a statement without proper warning?

A suspect making a statement without proper warning relates directly to the rights guaranteed by the Fifth Amendment, specifically the right against self-incrimination, and the procedural requirements established by landmark Supreme Court cases, especially Miranda v. Arizona. If law enforcement fails to provide the necessary warnings, which inform the suspect of their rights to remain silent and to have an attorney present, any statement made by that suspect during interrogation is generally inadmissible in court. This principle operates to protect the suspect's rights and ensure fair legal processes.

Consequently, when a statement is obtained without the requisite warnings, it cannot be used during trial as it is deemed unreliable and potentially coerced. This upholds the integrity of the judicial system by preventing the prosecution from benefiting from statements made in the absence of appropriate legal safeguards for the suspect.
