What legal principle protects individuals from being tried twice for the same crime?

Double jeopardy is a legal principle embedded in the Fifth Amendment of the United States Constitution, which prohibits an individual from being prosecuted again for the same offense after an acquittal or conviction has occurred. This principle is designed to protect individuals from the emotional and financial toll of multiple trials for the same conduct, ensuring that once a verdict has been reached, the matter is considered resolved under law.

In essence, double jeopardy safeguards against government overreach and the possibility of abuse, where the state might seek to convict an individual repeatedly until a desired outcome is achieved. It establishes a clear boundary for the judicial process, reinforcing the finality of criminal verdicts and maintaining public trust in the legal system.
