use. Safeguards of justice (Amendments 4, 5, 6, 7, and 8) The Fourth Amendment (1791) protects people against unreasonable searches and seizures of either self or property by government officials. A search can mean everything from a frisking by a police officer or to a demand for a blood test to a search of an individual's home or car. A seizure occurs when the government takes control of an individual or something in the possession of the individual. Items that are seized often are used as evidence when the individual is charged with a crime. It also imposes certain limitations on police investigating a crime and prevents the use of illegally obtained evidence at trial. The Fifth Amendment (1791) establishes the requirement that a trial for a major crime may commence only after an indictment has been handed down by a grand jury; protects individuals from double jeopardy, being tried and put in danger of being punished more than once for the same criminal act; prohibits punishment without due process of law, thus protecting individuals from being imprisoned without fair procedures; and provides that an accused person may not be compelled to reveal to the police, prosecutor, judge, or jury any information that might incriminate or be used against him or her in a court of law. Additionally, the Fifth Amendment also prohibits government from taking private property for public use without "just compensation", the basis of eminent domain in the United States. The Sixth Amendment (1791) provides several protections and rights to an individual accused of a crime. The accused has the right to a fair and speedy trial by a local and impartial jury. Likewise, a person has the right to a public trial. This right protects defendants from secret proceedings that might encourage abuse of the justice system, and serves to keep the public informed. This amendment also guarantees a right to legal counsel if accused of a crime, guarantees that the accused may require witnesses to attend the trial and testify in the presence of the accused, and guarantees the accused a right to know the charges against them. In 1966, the Supreme Court ruled that, with the Fifth Amendment, this amendment requires what has become known as the Miranda warning. The Seventh Amendment (1791) extends the right to a jury trial to federal civil cases, and inhibits courts from overturning a jury's findings of fact.
