An experienced (5 years +) local attorney who focuses on criminal defense and DWI should know the courts, the system and the personnel who run the courts.  A wise attorney knows that being belligerent to to the courts is often harmful not only to the case being worked but having a bad reputation for being obnoxious or any other reason limits your attorneys ability to work the system to your favor.  In the end you are best served by an attorney who knows the law, the courts, the system and has professional relationship with all of the people who run the courts.
