Answer: A well-known person for doing a bad deed.
Explanation:
Double jeopardy is from the 5th amendment of the Constitution. The 5th amendment states, "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb . . . ."
Basically it means that if a person was tried once already and was found not guilty, he can't be tried again for the same offence (even if they find new evidence).
