What type of evidence is not admissible during a trial as upheld by the Exclusionary Rule?

The Exclusionary Rule is a legal principle that prohibits the use of evidence obtained in violation of a person's constitutional rights, particularly during searches and seizures without a warrant or probable cause. This rule is designed to deter law enforcement from conducting illegal searches and to protect the integrity of the judicial process.

In the context of the options provided, evidence obtained without a warrant typically falls under this rule, as it suggests that the collection of this evidence may not have met the legal requirements set forth by the Fourth Amendment, which protects citizens from unreasonable searches and seizures. If law enforcement gathers evidence without following the proper legal protocol, such as obtaining a warrant based on probable cause, that evidence is considered tainted and generally inadmissible in court.

This focus on legality and constitutional rights ensures that trials are fair and that individuals are not convicted based on improperly obtained evidence. Thus, it is the evidence obtained without a warrant that is excluded from trial, aligning with the purpose of the Exclusionary Rule.
