Cops are people too. I would rather they be right that wrong, but I don't make a living pointing out where they were wrong. I still prefer they are right. No problem with people having to obey the law and live within the rules.This pains me, but the copper is right.
I dislike checkpoints because of my previously stated position of inefficiency. I agree the PR of a checkpoint is effective, as it has proven to be over the years, but I’ll also argue that publishing DUI arrest data on front pages would be just as effective, if not more so.
I understand the rationale, I just believe the courts are wrong on this one. It's a 4th Amendment violation, IMO.
The crux of this issue seems to be your disagreement with the courts on what is "reasonable" and why. The court has repeatedly said that the brief (<2min) stop of random cars at a checkpoint to look solely for impaired drivers is reasonable. The language in several court decision even hints that such checkpoints are necessary. Driving not being a protected right, coupled with the immense danger posed to the public posed by drunk drivers, there is minimal intrusion on a person's liberties. Of course this only holds true when a checkpoint is held as a pure impaired driving checkpoint, not masquerading as a way to check for suspended drivers, expired plates, equipment violations, etc.....
If we focus on the issue of driving not being a protected right, then how would an analogous situation work with people walking down a sidewalk being detained even briefly?
