Radley Balko says we'd be well served by doing so and makes the point rather well. If we allow cops to focus on impairment, rather than arbitrary numbers we'd likely see a drop in lives lost and actual dollar costs. We'd also see things like rights abusing check points disappear and that strikes me as a good thing, since they nab very few drunk drivers and usually serve to do nothing more than pad the local treasury. I do have a problem handing back a lot of discretionary power to the local cops, since much would depend on their subjective opinion on impairment. Guess there's a trade off no matter what. Regardless, good article and much to think about.
