When a person is arrested for DUI in Cherokee County the police will have their investigation and report. Without your own investigation, you are forced to rely on the conclusions of the arresting officer. Those conclusions generally do not have sufficient context to be fair to a person arrested for DUI. For example, a diabetic can exhibit manifestations of alcohol impairment if have a hyperglycemic or hypoglycemic episode. In other cases, people who have had physical injuries or concussion may not be able to perform field sobriety tests. In fact, they may even look impaired on video because of their medical condition. That is why your own independent investigation is needed in order to present your best possible defense.
