Under which amendment is a person protected from being tried for the same crime twice?

The Fifth Amendment to the United States Constitution includes a crucial protection known as the double jeopardy clause. This clause ensures that no person can be tried again for the same offense after a valid conviction or acquittal. The principle behind this protection is to uphold fairness in the legal system and to prevent the government from subjecting individuals to the emotional and financial burdens of multiple trials for the same crime. The amendment reflects a fundamental aspect of due process and recognizes the finality of court decisions.

In contrast, the other amendments listed deal with different rights and protections. For instance, the Fourth Amendment protects against unreasonable searches and seizures; the Sixth Amendment guarantees the rights of defendants in criminal prosecutions, including the right to a fair trial and counsel; and the Seventh Amendment concerns the right to a jury trial in civil cases. Thus, the Fifth Amendment specifically addresses the issue of being tried for the same crime twice, making it the correct answer in this context.
