The hallmark of the American justice system is that everyone is presumed innocent until the prosecutor proves otherwise. This means that the judge and jury must give you the benefit of the doubt and view the prosecutor's arguments skeptically until they are supported with evidence. This theoretically means that you have the advantage. In a perfect system, if you believed that the prosecutor was totally wrong, you could sit back and refuse to submit any evidence or arguments since the burden is entirely on the prosecutor. In reality, this probably isn't a good idea.
