You have questions and you want someone to listen to your side of the story. Every case is a little different and an attorney can help you sort out what's going to be important to the prosecutor, the judge, and the jury. In many cases there are just two witnesses: you and the police officer. Unfortunately, it's your word against the police officers, but maybe an attorney can find holes in the police officer's story. Sometimes cases get dimissed that way. If there are no holes, then sometimes an attorney can get you a better outcome than if you represented yourself--called pro se. Or, maybe in your situation there were a lot of witnesses--like at a party, a bar, or a club and your not quite sure what happened because it was loud, dark, and everyone has a different story about what happened. Maybe everything happened so fast, your unsure what happened, and you don't know if you should fight or plead guilty. Maybe in your situation you feel like you were not doing anything wrong at all and you want an attorney in your corner just to make sure your not getting treated unfairly. Maybe you don't quite trust law enforcement or understand how the "system" works. It's allright. Most attorneys didn't understand how all this works until they went to law school, or maybe even after law school. The point is that every little fact and detail of your situation is important because one little thing can mean the difference between your case getting dimissed or going to trial. Its important to tell your attorney as much as you know or tell him or her where he can find out! Always be honest with your attorney because he is defending you based on what you have told them. Imagine preparing for the championship game by watching video of the wrong team. Your game-plan will be all wrong.
