  Drunk drivers are every bit as dangerous as the so called "real bad guys".  They are armed (not just with their 2000+ lbs cars), short tempered and lack the judgment and self-control that someone who is not impaired.  There are just as many fights with drunk drivers as there are with the other bad guys.  
  Where are these minor first aids stations going to be and who is paying for them?  A breathalyzer is just as acurate as a blood test or a urine test with a trained person operating the machine or someone who is trained to draw blood, making sure not to use an alcohol pad to clean the area prior to drawing the blood.
  I believe it is in Saudia Arabia that they do execute first time DWI drivers other countries have minium 10yrs in prison and other punishments that really fit the crime.
