I can't stress enough how important this window of time is for a criminal defense attorney. It gives me a chance to speak with the prosecutors, shedding light on issues they may otherwise ignore. By the time a filing decision is made, the prosecutor may be presuaded by my arguments, so much so that they reduce the felony charge to a misdemeanor charge. While there is still an open criminal case, it is a misdemeanor. And believe me - it is much better to be in County Court dealing with a misdemeanor than in Circuit Court dealing with a felony. You can't be sent to state prison for a misdemeanor, but even the lowest degree felonies carry five years.
Do yourself a huge service if you or someone you know is arrested. Call a Miami or Broward criminal defense attorney as soon as possible.
