Here is the problem. No drunk driver gets in their car with the intention of killing someone. Drunk drivers pose a greater threat to the safety of others than those with their judgment intact. I can guess by your callus that you have never been lost someone due to a drunk driver. My Father chose to drive drunk and killed himself and my Mother. You need to consider that driving drunk puts everyone on the road at greater risk of injury or death. I don't understand how you cannot see how the two correlate...
