Like speeding or any other crime, you are not going to catch everyone. But if you are looking for drug dealers I would say you need to look in those areas where they are known to congregate. Same for drunk drivers. If reducing hazard to the public is the real goal. It would make sense to go where you have the greatest impact.
In business it is called utilizing your resources for their highest and best use.
Those driving after drinking at a private residence are still on the street and bound to pass a policeman on the way hom anyway.
