Clermont, FL Criminal Defense Law Firms & Lawyers

The burden is not on a defendant to prove his/her innocence.  The burden is on the state to prove guilt.  However, often the state's burden is very minimal -- so it's always good when a defendant has something that can prove innocence if, despite being innocent, the state was able to meet its initial burden.  However, often a Defendant is unable to adequately use his evidence showing innocence except at trial.  Sometimes if the evidence of innocence is apparent and strong, the state can be persuaded to drop the charge before it goes to trial.  But that is something you need to discuss in great detail with your attorney before making a decision on how to handle the evidence you have.  I definitely recommend against you, personally, talking to the prosecutor or law enforcement officers -- even if you believe your evidence is very strong. I believe that would be a big, potentially irreversible, mistake.
