In the state I live the police can not force you to give up blood in a DUI case. What they can do is take away your license for a year if you refuse. Since you don't have a constitutional right to drive or a driver's license they can do this without running afoul of the state or federal constitution. A subtle difference but then the law is filled with such subtleties. You are not wrong though, as far as we know now bio-metrics are not protected. But I think this is just until some ruling comes down from a superior court and sets a precedence one way or another. I'm sad to say I won't be surprised whichever way it turns out though.
