What must happen to evidence obtained without informing a suspect of their rights?

The correct answer is that evidence obtained without informing a suspect of their rights may be thrown out due to the exclusionary rule. This rule is a legal principle that prevents evidence collected in violation of a suspect's constitutional rights—specifically, the right against self-incrimination and the right to counsel—from being used in a court of law.

In situations where law enforcement fails to provide a Miranda warning, which informs a suspect of their rights during an interrogation, any statements made by the suspect or any evidence derived from those statements may be deemed inadmissible. This doctrine aims to deter police misconduct and protect the integrity of the judicial process.

Understanding the exclusionary rule is crucial, as it underscores the importance of protecting individual rights during legal proceedings. This serves not just to maintain fairness in the legal system but also to ensure that law enforcement adheres to proper procedures when gathering evidence.
