Which constitutional amendment protects against double jeopardy?

The Fifth Amendment is the correct choice because it specifically includes the protection against double jeopardy, which is the legal principle that prohibits an individual from being tried twice for the same offense. This protection is fundamental to ensuring fairness in the legal system and preventing the government from subjecting an individual to multiple prosecutions for the same act, which could cause undue stress and hardship.

In addition to this protection, the Fifth Amendment also encompasses other significant rights, such as the right against self-incrimination and the right to due process. This context highlights the importance of the Fifth Amendment in safeguarding individual liberties within the judicial system.

The Fourth Amendment, on the other hand, primarily addresses issues of search and seizure, protecting individuals from unreasonable searches by the government. The Sixth Amendment guarantees the rights of criminal defendants, such as the right to a speedy trial and the right to counsel, but does not specifically address double jeopardy. The Fourteenth Amendment is crucial for ensuring due process and equal protection under the law but is not directly concerned with the issue of double jeopardy.
