Your rights, as protected by the Fifth Amendment, is an important part of criminal law.
The Fifth Amendment of the U.S. Constitution, in part, provides that "no person ... shall be compelled in any criminal case to be a witness against himself." The application of this Self-Incrimination Clause though has been expanded by the U.S. Supreme Court to apply not only to criminal proceedings and pre-trial proceedings in criminal matters, including police-station interrogations, but also to "any other proceeding, civil or criminal, formal or informal, where his answers might incriminate him in future criminal proceedings." The Constitutional provision also prohibits prosecutors from making reference to a defendant's refusal to take the stand as probative of guilt. So long as the government is compelling potentially incriminating speech—either before a jury or a Senate Committee—the right can be invoked.
The Self-Incrimination Clause of the Fifth Amendment to the United States Constitution guarantees that no one has to testify against himself in any criminal proceedings. This is one of the most well known phrases in the entire Constitution, due to the popular concept of "Pleading the Fifth" or "Taking the Fifth" that is often used in movie and television courtroom scenes, and because of the famous "Miranda Warning," which is spoken to suspects before an interrogation.
The Miranda Warning begins, "You have the right to remain silent..." It is a Constitutional guarantee that people do not have to answer questions or give up information that might be used against themselves in legal proceedings. Its main purpose is to prevent the government from pressuring someone into a confession through the use of force, torture or trickery. Any confession that is procured by these means is usually taken by the court as faulty.
Confessions of this sort are usually given unwillingly and are very unreliable. Someone might tell the government what it wants to hear to prevent a threatened punishment. For example, if the government said, "Tell us you committed this crime, or we are going to deport your Asian wife," the person might say he committed the crime, whether he did or not.
If someone takes advantage of his right to "plead the fifth," they cannot be accused by the prosecutor of being guilty of the alleged crime simply because he relied on the Self-Incrimination Clause of the Fifth Amendment.
Likewise, if a person does not take advantage of the Self-Incrimination Clause, and instead takes the stand on his own behalf, he cannot later refuse to answer questions on cross examination. He must "plead the fifth" first or take the stand, he cannot do both.
Forced confessions are always thrown out of court and they cannot be used against anyone. Also, evidence obtained as a result of a forced confession cannot be used in court against the person either. You may have realized that someone could actually be guilty and confess their guilt under strong coercion of the government and this evidence would then have to be thrown out. A guilty person might go free in this circumstance. Why would the Founding Fathers have put a provision in the Bill of Rights that might let criminals go free? The answer is that they were trying to protect the innocent, as well as convict the guilty. The value of protecting innocent people is so high that laws are sometimes passed that might let a few criminals go unpunished.
Any testimony that is unjustly gathered by a state government cannot later be used against the person in a federal trial. Likewise, illegally compelled testimony in a federal court cannot be used against someone later in a state court. Any information gathered in an interrogation cannot be used in court if the witness was not informed of his rights before the interrogation. It also gives a suspect the right to refuse to testify about indirect items that might aid the prosecution by providing a link in a chain of events that could lead it to discovering the suspect's guilt.
The Self-Incrimination Clause of the Fifth Amendment can only be relied upon by individuals. It cannot be used by an organization, such as a corporation, to refuse testimony in court. It also cannot be used to avoid testifying about someone else's guilt. It can only be relied on if the testimony would incriminate the person giving the testimony.
