I am currently debating this with my friend.
So in a hypothetical situation, Person A was falsely accused of a horrible crime, like say, rape or murder. However, Person A was found guilty anyway because of a lack of evidence to defend themselves. Person A serves some time in prison and is eventually released years later when evidence is found that they are not guilty.
My friend's claim is that Person A can now go out and fulfill this crime that they were falsely accused of with no legal repercussion. As they were already technically punished for this crime. He claims that double jeopardy laws prevent this person from being prosecuted twice on the same crime.
My claim is that Person A can not fulfill this crime without legal repercussion. My reasoning is because even though they already served time in prison for this crime, Double Jeopardy laws regard this as a second and separate punishable offense instead of a continuation of the first false accusation.
