Double jeopardy is the prosecution of a person for an offense for which he or she has already been prosecuted. The double jeopardy clause, which is in the Fifth Amendment of the United States Constitution, was designed to protect an individual from being subject to trials and possible convictions more then once for an alleged offense. The idea was not to give the State too much over the individual, this way no individual will be subject to embarrassment, expense, and ordeal against being tried for an alleged offense more then once. It also reduces the possibility of someone innocent being found guilty.

The trial judge told the jury that they could find Green guilty of arson under the first count and either first degree murder or second degree murder under the second count. Second degree ...
