Gwinnett County Commission Chairman Charles Bannister’s arrest raises an important question: Since the arresting officer says the standard field sobriety tests indicated Bannister was impaired, why did the State’s own breath test indicate no alcohol in Bannister’s blood?The State can’t have it both ways; they can’t argue, as they do in virtually every case, that “the machine was working properly because it spit out a reading,” yet in this case the machine was not working properly because it registered a 0.00. Based on this case, why would anyone ever trust the Intox 5000? Either the officer’s evaluations of the field tests are incorrect, or the Intox is incorrect.
