The "exclusionary rule" was first developed in Mapp v. Ohio. If there was an illegal search/seizure, any evidence obtained as a direct result of that action is "the fruit of the poisonous tree" and should be excluded. However, the USSC has progressively weakened the fourth amendment protections available to criminal defendants, and most cases fall into an exception of some type, allowing the evidence in.
