Why would you even try to argue that sobriety checkpoints don’t reduce DWI? Of course they do. There are at least 3 detailed studies available on-line to prove this. People adapt when the possibility for getting caught increases.
The question shouldn’t be: do they work? It should be, Are they consitutional? Sadly... our current SC says, “yes”.
I think my point is blowing over your head... Of course if everyone in town knows that a checkpoint is being conducted, most drunks will either not drive drunk that night or drive somewhere else. So yes, some IDIOTIC STUDY will conclude that the checkpoint "deduced" DUI's that night by 80% and checkpoint reduce drunk driving. But that's utterly meaningless when compared to the number of impaired drivers that those same officers would stop during routine patrols after seeing signs of impairment.
