Even if you are detained (a/k/a arrested), you should know the drill. Full name, legal address, date of birth and Social Security number is all the info that you legally have to provide when you are "booked". After that, shut up and lawyer up. Remember, anything you say can and will be used against you in a court of law.you shouldn't even talk to cops unless you are being detained, if any cop walks up to me and tries to ask questions I ask them "am I being detained" , and if he says no then I don't have to answer any of his questions.
