Do DUI Standardized Field SobrietyTests Convict the Innocent?
A Colorado Doctor claims that DUI Standardized Field Sobriety Tests convict 3 out of 4 innocent people.  DUI Standardized Field Sobriety Tests include the Horizontal Gaze Nystagmus, the 9 step Walk and Turn, and the One Leg Stand. The Doctor compares the accuracy of DUI standardized field sobriety test with courthouse security metal detectors.  He argues that they are great at finding guns but also find things like phones and car keys.  The machines can not discriminate between the illegal and legal.  The Doctor surmizes that DUI Standardized Field Sobriety Tests do the same thing.  These DUI Standardized Field Sobriety Tests can not discriminate between the impaired by alcohol and the generally uncoordinated.  He claims that the "validation studies" performed by NHTSA are biased because they do not test a representative sample of the population but only test those driving late at night who smell of alcohol.  The 1998 San Diego validation studies claim 90% accuracy but the Doctor claims the studies own data shows that the test indicate clues of impairment in over 63% of people below the legal limit.  His website is fieldsobrietytest.info.  The raw data is available below just click the underlined more tab.  When reviewing the data notice that the breath test under the legal limit for Georgia DUIs and Metro Atlanta DUIs are bolded.
