Final answer:
Double jeopardy is a legal principle that protects individuals from being prosecuted or sentenced twice for the same offense.
Step-by-step explanation:
Double jeopardy is a legal principle that protects individuals from being prosecuted or sentenced twice for the same offense. According to the Fifth Amendment of the United States Constitution, once a person has been found not guilty of a crime, they cannot be tried again for that same crime. However, there are exceptions to this rule, such as when the second prosecution is conducted at a different level of government or involves a different offense.
