A new way to get you

Everyone knows that if you are pulled over by a police officer, and you are asked to give a breathalyzer, you can refuse. You WILL go to jail, and then have your license suspended for 6 months, but that's the price you pay for freedom. Now the fine folks who brought you unfair, bring you a new way to get ya. Fingerprint devices will be carried by officers in select locations very soon, and based on the success, maybe all of the city. The article referred to can be found here.
The official use for them will be to help identify suspects in crimes by capturing their fingerprint and sending it to a database. Then the database will kick back any information it finds, or none in that instance. Is it just me, or is that a violation of the Constitution of the United freakin States of freakin America???? Although it doesn't DIRECTLY violate the Bill of Rights, it is obvious based on the wording in the Constitution that this kind of power would not be OK. Of course, i am talking about people who could have no idea that things would be this advanced, so I'm assuming quite a bit. But still, does this not fall into the realm of unreasonable search and seizure? How can the cops just decide that I'm suspicious and run my prints for say, a speeding ticket? I guess the same reasoning will be used that is used for the right to automatically run the plates of your car and see if you are a bad citizen. And what a surprise that this was worked out with the homeland security office, and no, I won't capitalize something that is the reincarnation of Hitler's Gestapo.
The police will have to ask consent to use the scanners on the suspect, but if they refuse, and I quote Matt Simpson, "As long as people are voluntarily doing it, it could save people from going to jail". Pretty reminiscent of the breathalyzer test, if you ask me. so the one big question that pops into my head is thus. How long, because this will be very successful, will it be until this is standard operating procedure for all stops?
