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.
There are at least 3 detailed studies available on-line to prove this
Ok so produce the links.
Of course, there is no study that can show the relative statistics compared to what WOULD happen if the officers were out searching for people with probably cause...
I get your point.
I’m 100% against random check points... but, common sense tells me... if they’re done enough, they would work. At least, in the small area where applied. If they stop everyone on every street... drunk driving will definitely decrease. ALL driving will decrease!
I just happen to believe that checkpoints are
1) not cost effective, and
2) unconstitutional.
