Not that I do or don't agree... My current operating theory is that investigators may use a "rag doll" view: they can't compel you to admit or divulge anything, but they can make use of your limp uncooperative (but not resisting per se) body. They may note your biometrics (eye color, iris pattern, hair samples, fingerprints, etc), doing so non-invasively (no blood samples unless you're already bleeding); as such they could take your hand and press your finger onto a fingerprint reader, just as they are allowed to gather prints for a background check without a warrant (AFAIK). Corrections welcome.
