Client stopped by police for failing to signal turn exiting traffic rotary. Arresting officer alleges client fails two standard field sobriety tests. Testimony regarding failed Horizontal Gaze Nystagmus (HGN) test excluded for lack of proper foundation. Evidence of .16 BAC blood test excluded as government fails to produce actual gas chromatograph test results, relying only upon transcription of test results recorded by lab technician. Not guilty verdict following trial.
