What does the phrase innocent until proven guilty mean in American law?
Until they have all the evidence to prove you have committed the crime you can not be charged for it
I believe that you might be thinking of the French system of justice. There, you are considered guilty until you can prove yourself innocent. In English jurisprudence it is the opposite way around - innocent until proven guilty. That is correct but the answer that you are looking for is the 'admiralty courts'
