You know your statement makes no sense. A checkpoint takes the drunk driver off the road and charges him for that offense.
Do you want to give the Police power to follow this guy 24/7 for a DWI? Because if you don’t, which I don’t, you can’t stop him from drinking and getting into a car again. But without those five checkpoint arrests he could have killed 5 times.
He has now served time and has no license. But you can’t stop him from hopping into a borrowed car and driving drunk again.
