And I suppose that they have the right to tap your phone calls or emails because there might be some illegal activity going on there, as well?
Friend, I just checked…and the 4th Amendment to the Constitution has not been repealed yet.The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and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.
While you are right that police can have a DUI checkpoint, this was not a DUI checkpoint. While you are right that driving is a privilege, they do not have the right to search your person (blood, breath, saliva) unless you have given them reason to suspect that you are under the influence (i.e., probable cause). Even in Virginia (I’ve dealt with Virginia checkpoints before and have been stopped. They asked to see my D/L and then wished me a good evening and safe drive).
I suppose you also don’t have a problem with TSA VIPR Teams checking people on the Metro, in train stations, or highways? How about as a pedestrian? (After all, walking on a sidewalk is a privilege, not a right. Do you know that each and every terrorist in the world has been a pedestrian at one point in time or another??? Hmmmmm??? Do you know how many lives they’ve saved???)
