In fact, officers of the law who conducted unlawful searches or seizures of property could be subject to prosecution under state or statutory law, and in some rare cases, may face criminal charges ("Alternatives to the Exclusionary Rule," n.d.). The exclusionary rule does sometimes constrain police behavior in criminal cases, potentially preventing the acquisition of evidence in "good faith," in the presence of "exigent circumstances," or even when probable cause can be retroactively determined ("Alternatives to the Exclusionary Rule," n.d.). Therefore, the Exclusionary Rule should not be banned; quite the contrary, it prevents abuses of power or misconduct by law enforcement.

Known as the "fruit of the poisonous tree" doctrine, courts may suppress all evidence connected with an unlawful search and seizure to protect the rights of the defendant to a fair trial. The Exclusionary Rule and its corollary "fruit of the poisonous tree" are occasional thorns in the side of law enforcement, and often make the task of evidence gathering difficult. However, the difficulty of performing the roles and duties of law enforcement and state…
