Answer to Question 1
For many years, U.S. courts exercised little control over the operations of criminal justice agencies, believing that their actions were not an area of judicial concern. This is known as the hands-off doctrine. In the 1960s, the Warren Court became more active in the affairs of the justice system. Each component of the justice system is closely supervised by state and federal courts through the law of criminal procedure, which sets out and guarantees citizens certain rights and privileges when they are accused of crime. Procedural laws control the actions of the agencies of justice and define the rights of criminal defendants. The most important due process laws are in the Bill of Rights; specifically, the Fourth, Fifth, Sixth, Eighth Amendments and the 14th Amendment, which bound Bill of Rights to the states. Procedural rights protect defendants from illegal searches and seizures and overly aggressive police interrogations. The exclusionary rule states that such illegally seized evidence cannot be used during a trial.
