No. If you're under arrest, you'll generally want to help them identify you properly (unless you don't, in which case going through the system as a John Doe [1] is an option and I know people who this worked quite well for) and state that you won't answer questions without an attorney. The act of asking for one gives you protections. Likewise, the police may read you your Miranda rights and try to get you to sign something saying you know and understand them. You should refuse to sign, stating that you won't sign anything without a lawyer. Signing it opens the door for further questions and a chance your answers can be used in court. Not signing it will generally lead to them skipping the questions, as there's little point. [1] edit: to do this you refuse to give any name. DO NOT give a false name like "John Doe" - that's merely what they'll put on the paperwork if you refuse to give a name. Giving a false name is pretty much always a bad idea. Note that generally refusing to not give your name is probable cause for arrest in many jurisdictions and I believe may even be a misdemeanor in some places. I think it's generally only a reasonable route if the arrest was clearly illegal and disclosing your real name might make you a target for other reasons (e.g. immigration status). I do know someone who wasn't a citizen who was arrested while engaging in protected first amendment activities and refused to say a single syllable (lest their accent give away their status) and they were released as a john doe at their arraignment. But yes, YMMV.
