Please bear with my incomplete knowledge of law and finance.

In criminal cases, the ones where a person gets murdered/beaten/robbed/kidnapped, mostly depend upon the prosecution proving the defendant guilty. If John Doe claims that he has been hurt, in the above stated ways+ https://twitter.com/thegodfather701/status/1311943523256750081

by Jane Doe, he provides evidences and witnesses against the accused. If proven, Jane Doe is penalized according to the constitution or per the law.

On the other hand in (white collar) corruption cases, which are defined as "loss of integrity or purity, wickedness & bribery" +

it is the *defendant* who has to provide evidence, documents of where, when and how they earned the money that is being challenged in the court of law. They burden of proof is completely on the the defendant and if it is not given to the court in a specific time span +

they are guilty and penalized.

So tell me again, who was not able to prove what?
