Obviously they work at catching DUI. That is not the issue.
The issue is it ok to have them.
The issue is it ok to have one rule of evidence for kidnapping, murder, rape, sexual assualt, theft, assualt, trespass, and all other crimes, but to have another for DUI?
Is it ok to give a DUI to someone who is asleep in the car with the keys in thier pockets?
Is it ok to stop every car on the highway to search for someone that stole a gun?
Is it ok to test someones hands for gunpowder residue without allowing their lawyer to be present? Is it ok to test someone for alcohol without that same lawyer present?
The question is not wether they are helpful or life savers the question is wether or not they violate our consitutional rights.
I have no problem in the world at all with arresting and convicting and punishing, drunk drivers. It just cant be done as a seperate and outside issue uneffected by the bill of rights.
Again I dont know if you read the whole thing, I am not against DUI's or DWI's, I am totally against people being proven guilty without a trial.
The whole the only people that suffer are the ones that have done something wrong is not right. Our country was not founded on that principal. Hundreds of thousands havent died to say, you have nothing to fear from your government if you havent done anything wrong.

See 4,5, and 6
They were written very very clearly in plain and simple english for a reason. These RIGHTS were bought with many lives. Its not right to give them away.
It doesnt say The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized BUT if you havent done something wrong you have nothing to worry about.
It's NOT your fault that you were speeding, it's society's fault.
