The first Amendement of the Bill of Rights states that:
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.
All policemen upon graduating from the police academy swear an oath to uphold the Constitution against both enemies foreign AND domestic. This oath would hold those policemen to protects the rights of the citizens they work for. That those policeman would swear that before a paycheck is delivered that they will defend these documents against any and all persons who would trample it. Persons to include, criminals, thugs, common citizens, lawyers, judges & politicians. But for some reason American citizens are being detained with absolutely NO PROBABLE CAUSE and interrupted based on an order to stop cars to check for driver's who might be drinking. Now that sounds like a very noble act but there can be no justice derived from an injustice.
People buy knives all of the time, and some even use them to murder innocent people, yet the courts do not feel that it is necessary to institute a program by the police to put all knife buyers under a psychological evaluation. But they do however feel that it is justifiable to stop ANY American citizen and have them submit to a search without any probable cause what so ever. You are secure in your vehicle just as you would be in your home. A policeman cannot just open any car door and search the contents of it without probable cause just as no citizen would allow a policeman to search his home with there being a signed search warrant. There is no difference between the two no matter the cause. It's not the ends which justify the means no matter how many judges would like to believe that we are a nation of men. The fact of the matter is that we are a nation of laws. And if we do not hold those accountable who would break the law then we cannot entrust those with the duty to defend our rights affirmed in the Bill of Rights. The same goes for taking an oath to defend the Constitution when you don't understand what it is that is written in the Constitution.
There will always be drunk drivers as there will all be murders, rapists and thugs. Each of the for mentioned kind of people all use tools but the most common factor between them are the fact that neither cares about the rights of others.
To be inconvenienced and detained unlawfully because of the shortcomings of a policeman's lack of investigatory skills is tyrannical. You must have probable cause to detain an American. You must have reason to believe that the American is about to commit a crime or has committed a crime. You cannot blatantly stop an American in hope that he doesn't know his rights and trick him into incriminating himself.
Sure I believe that DUI are a terrible reality but there is no reason to suspect an innocent man and then force him to stop his vehicle so a policeman can visually snoop in hopes of smelling alcohol.
My solution to these Unconstitutional road blocks is simple. Do your job by priorities. Defend the Constitution and help to protect the rights of Americans without having to violate the rights of those Americans who abide by the laws.
Instead of doing a DUI Road Block, just hangout by the local gin mills and watch the drivers who leave the bars. At least then you might have enough probable cause to detain them and conduct a reasonable search.
Don't get me wrong, the citizens need the police. For God sake, there are a lot of unarmed Americans who are in favor of DUI Roadblocks that depend on the police for protection.
