I would hope that this requirement to answer is somehow challenged and found unconstitutional, but I don't have any expectation of that ever happening. Especially after the recent case that revised the Miranda
As a rule I do not talk to police. I do not acknowledge them if approached on the street, and if I am driving and get pulled over I give them the documents I am required to and do not say anything else. I certainly do not answer questions. I can't be accused of lying to the police if I do not say anything at all.
I don't put much faith into words on paper except when there is someone willing to enforce them with violence, which is why I generally follow the "written law", but last I checked the 5th amendment to the constitution was still part of the document that every officer swore an oath to uphold and defend. The government has plenty of armed enforcers willing to enforce their laws against the people, but the people have no enforcers to uphold the document that is supposed to protect us from them. When was the last time any of them went to jail for violating the constitution?
