So if you volunteer to walk into a police station without being under arrest, and choose to answer police questions, you do not need to be read your Miranda rights, the Supreme Court has held. You can, however, ignore or refuse a request to come in for questioning -- but police may then choose to arrest you.22 may 2013
What happens if I don't go in for questioning?
Answer NO QUESTIONS! If they have the probable cause to arrest you, they'll arrest you and interview you post-arrest, if you're silly enough to ignore the part about, “You have the right to remain silent.” If they don't have probable cause or you're a witness, they can't legally make you go anywhere.
