Step-by-step explanation:

It means that if the police conduct an illegal search or seizure without a warrant and find evidence of a crime, that evidence cannot be used against the defendant in court.
The purpose of the exclusionary rule is to deter law enforcement officers from conducting illegal searches and seizures. By excluding illegally obtained evidence from being used in court, it sends a message that the Fourth Amendment rights of individuals must be respected and protected.
The exclusionary rule plays a crucial role in containing the power of the executive branch. It ensures that law enforcement officers cannot violate individuals' constitutional rights and use the illegally obtained evidence to secure convictions. Through the exclusionary rule, the judiciary acts as a check on the executive branch, safeguarding individuals' rights.
